3 Description
The VCA710 is a single-channel, low-noise, low- power variable gain analog front end (AFE) optimized for high-performance signal conditioning. The VCA710 integrates two sub-blocks: a low-noise amplifier (LNA) with a fixed gain of 10V/V (20dB) and a variable gain amplifier (VGA) delivering high dynamic range and gain control flexibility. The LNA and the VGA blocks can be used independently or in conjunction based on the requirement. The VGA sub-block features a High Gain and Low Gain mode offering two gain ranges: –12dB to +40dB or –32dB to +20dB for optimizing output noise. The VGA supports both AC and DC coupled inputs as well as single-ended and differential inputs. The VCA710 features a fully differential output with an adjustable output common mode control feature. The VCA710 supports a wide-supply from 3.15V to 5.25V, temperature range of –55°C to +125°C, in a compact 3.5mm × 3.5mm 20-pin RGR (VQFN) package. The VCA710 is an excellent choice for applications like ultrasound, sonar, optoelectronic front-ends.

7 Detailed Description
7.1 Overview
The VCA710 is an analog front-end device that consists of two main blocks: a Low Noise Amplifier (LNA) with a fixed internal gain of 20dB, and a Variable Gain Amplifier (VGA). The LNA accepts both differential and single ended input signals and provides differential outputs. The LNA operated only with AC coupled signals. The VGA accepts both AC and DC signals, which can be either single ended or differential input. Both sub blocks can be used independently owing to the separate enable functionality and separate inputs and outputs. For users requiring DC coupled capability TI recommends to disable the LNA and provide inputs directly to the VGA.
7.2 Functional Block Diagram
The VCA710 allows gain control to a dynamic range of 52dB via a programmable voltage between 0V and 1V applied on the GAIN_ADJ pin. Beside the fine gain adjust VCA710's VGA block also provides a course gain setting via the HILO mode pin. With the analog gain control block and the HILO pin the VCA710 provides gain range either between –32dB to +20dB or from –12dB to +40dB. This makes the gain highly configurable for different application needs. The different gain buckets provide different trade-offs as shown in the Electrical Characteristics For high accuracy and tight gain error tolerance TI recommends applying a 0.5V external reference on to the VREF pin. For applications where gain accuracy is not important the device includes an internal reference voltage which can be used by keeping the VREF pin floating. The VOCM_ADJ allows output common mode control to allow the common mode to be matched with that of the ADC.

7.3 Device Functional Modes
The VCA710 operates in several functional modes determined primarily by the control pins and the amplifiers supply conditions. These modes define how the device shapes, scales, and conditions signals across AC and DC applications. Normal Operation Mode In this mode, the device functions as a single-channel, low-noise variable-gain amplifier (VGA). Both the low- noise amplifier (LNA) and VGA paths operate from a 3.3V to 5.25V supply, providing low noise and high dynamic range. This is the default mode whenever the device is powered and all pins are within valid operating ranges and all the sub-blocks are enabled.
- LNA + VGA enabled – In this mode EN_ VGA is high and EN_ LNA is high, LNA is AC coupled and VGA is either AC or DC coupled.
- LNA only enabled – In this mode EN_LNA is high, EN_VGA is low. Only LNA is in enabled state and VGA is disabled. The LNA block is used independently as a 0.9nV/√Hz input referred 20dB gain block.
- VGA only enabled – In this mode EN_VGA is high, EN_LNA is low. Only VGA is in enabled state and LNA is disabled. For applications where internal LNA of the VCA710 cannot be used TI recommends using this mode. Gain Modes The VCA710 supports two selectable gain-scaling behaviors, controlled by the HILO pin. This pin selects an internal 40dB/20dB fixed gain amplifier (FGA).
- High Gain mode / FGA = 40dB (HILO = 1) – Gain range: –12 dB to +40dB – Optimized for higher overall gain, better distortions, better input and output noise at higher gains. – Suitable for broadband front ends and low-level inputs that require wide scaling.
- Low Gain mode / FGA = 20dB (HILO = 0) – Gain range: –32 dB to +20dB – Optimized for applications requiring lower noise at lower gain and better voltage offset. – Suitable for higher ENOB ADC. Besides the above two gains from the FGA the GAIN_ADJ pin accepts an analog control voltage that smoothly adjusts attenuation from 0dB to -52dB via an interpolator. Overall VGA gain = interpolator gain + FGA gain. Input common mode selection for VGA
- Input common mode generated internally, VICM enable – In this mode EN_VICM = 1, input common mode is set to mid supply internally and inputs are expected to be AC coupled.
- Input common mode set externally, VICM disable – In this mode EN_VICM = 0, input common mode is set externally via applied input signal. This mode allows DC coupling of input signals. The common mode = (VIP_VGA + VIM_VGA) / 2. Make sure the input common mode is within the specified range specified as per the electrical characteristics. www.ti.com VCA710 SLOSEB2 – FEBRUARY 2026 Copyright © 2026 Texas Instruments Incorporated Submit Document Feedback 17 Product Folder Links: VCA710 ADVANCE INFORMATION
8 Application and Implementation
Information in the following applications sections is not part of the TI component specification, and TI does not warrant its accuracy or completeness. TI’s customers are responsible for determining suitability of components for their purposes, as well as validating and testing their design implementation to confirm system functionality.
8.1 Typical Application
8.1.1 Ultrasound Flow Meter Front-End
The VCA710 can be used as a complete front-end IC for ultrasound flow meters. With an input referred noise of 1nV/√Hz, maximum gain of 60dB and a dynamic range of 52dB, the VCA710 can be used to interface an ultrasound sensor, with an appropriate ADC.

8.1.2 Design Requirements
Table 8-1. Design Parameters PARAMETER VALUE Input signal range to the VCA710 from the ultrasound sensor 100μVPP to 1VPP Min required SNR for measurement At least 20dB at 100μVPP Frequency of measurement / Transducer frequency 1MHz Input Impedance High
8.1.3 Detailed Design Procedure
The LNA sub-block inside the VCA710 supports both single ended and differential input. The ultrasound transducer can be connected either way as per the requirement to the input of the LNA. Beside providing a low input referred noise and an additional gain of 20dB, the LNA block also provides high input impedance making the part an excellent choice to be interfaced directly with high output impedance sensors.

Product Folder Links: VCA710 ADVANCE INFORMATION
Achieving an SNR of > 20dB is most challenging when the signal to the LNA is the lowest (100 μVPP in this case). Since our frequency of interest is confined in and around 1MHz TI recommends adding an additional Band Pass Filter between the LNA and the VGA sub blocks. This limits the overall integrated noise carried forward towards the ADC. Refer to the application section of LOG300 8.2.1 Ultrasonic Distance Measurement for recommendation and design of a 1MHz band pass filter. Assuming a bandpass filter of Pass Band frequency of 800kHz with a single pole roll of response, the overall integrated input referred noise of LNA is: V n I nput re f err ed = 1nV / H z × 800 k H z × 1.57 (1) V n = 1.4 µ V r ms (2) V n pe a k t o peak = 6 × 1.4µV r m s = 8.4 µ V pp (3) The 4.5nV/√Hz input referred noise of the VGA sub-block translates to 0.45nV/√Hz at the input of LNA allowing us to conveniently ignore it in our calculation since its ~ 1/3 rd the LNA's own input referred noise. 1.57 is the brickwall correction factor for single-pole role off. With a total input referred noise of 8.4μVPP, the achieved SNR at 100μVPP at input is SNR = 20 × log × 100 µV P P 8.4µV PP = 21.4 dB (4) To protect the LNA from high input voltage during burst / Tx mode or other unseen circumstances TI recommends to add a back to back diode at the input of the LNA to clamp the input voltage to 1.4VPP max. The EN_VICM is enabled by connecting the pin to VCC_VGA since this is an AC coupled application. Enabling the EN_VICM allows the VGA sub-block to set the internal common mode voltage appropriately. Applying an appropriate voltage between 0V to 1V on the GAIN_ADJ pin and toggling the HILO pin allows an overall gain of the VCA710 ( LNA + VGA ) from –12dB to +60dB, Using the VOCM_ADJ pin an appropriate output common mode voltage can be set as per the ADC requirements. With ADC requiring 0V common-mode voltage, TI recommends using VCA710 in bi-polar/split supply mode to enable 0V common mode support.
8.1.4 Optical Receiver Front-end
VCA710 can be used as a variable gain amplifier in the receive path of an optical signal chain. Since the VGA sub block of the VCA710 supports DC coupled connections the preceding TIA is directly connected to the non inverting input of the VGA. By shorting the EN_LNA to VEE_LNA, the LNA gets disabled thereby reducing overall power consumption. The VCA710 supports single ended DC input and translates the applied DC input to a differential output based on the applied GAIN_ADJ voltage. By applying an additional voltage on the VIM_VGA design for input common mode voltage to be within the tolerable input common mode voltage range. www.ti.com VCA710 SLOSEB2 – FEBRUARY 2026 Copyright © 2026 Texas Instruments Incorporated Submit Document Feedback 19 Product Folder Links: VCA710 ADVANCE INFORMATION

8.2 Power Supply Recommendations
A multilayer board with power and ground planes is recommended. Pour any blank areas in the signal layers with ground plane. Decouple the power supply pins with surface-mount capacitors as close as possible to the respective pins to minimize impedance paths to ground. Decouple the LNA power pins from the VGA supply using ferrite beads to avoid crosstalk.
8.3 Layout
8.3.1 Layout Guidelines
The VOP_LNA and VOM_LNA output traces must be as short as possible before connecting to VIP_VGA and VIM_VGA. Isolation resistors must be placed near to the respective output pins to mitigate loading effects of capacitance of connecting traces. Removing GND pour below these traces helps further reduce capacitance loading. Signal traces must be short and matched to avoid parasitic effects. With complementary signals, symmetrical layout helps in maintaining waveform balance. PCB traces kept adjacent when running differential signals over a long distance help cancel the mutual inductance component. Stitching of vias is preferable to reducing inductance Shielding and decoupling is recommended for all the analog pins like GAIN_ADJ, VREF, VOCM_ADJ as they may be sensitive to parasitic coupling.

Testing and final process, including without limitation quality assurance, reliability performance testing, and/or process qualification, may not yet be complete, and this item is subject to further changes or possible discontinuation. If available for ordering, purchases will be subject to an additional waiver at checkout, and are intended for early internal evaluation purposes only. These items are sold without warranties of any kind. (3) RoHS values: Yes, No, RoHS Exempt. See the TI RoHS Statement for additional information and value definition. (4) Lead finish/Ball material: Parts may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead finish/Ball material values may wrap to two lines if the finish value exceeds the maximum column width. (5) MSL rating/Peak reflow: The moisture sensitivity level ratings and peak solder (reflow) temperatures. In the event that a part has multiple moisture sensitivity ratings, only the lowest level per JEDEC standards is shown. Refer to the shipping label for the actual reflow temperature that will be used to mount the part to the printed circuit board. (6) Part marking: There may be an additional marking, which relates to the logo, the lot trace code information, or the environmental category of the part. Multiple part markings will be inside parentheses. Only one part marking contained in parentheses and separated by a "~" will appear on a part. If a line is indented then it is a continuation of the previous line and the two combined represent the entire part marking for that device.
