Description
The TSV620, TSV620A, TSV621, and TSV621A are single operational amplifiers offering low voltage, low power operation, and rail-to-rail input and output. With a very low input bias current and low offset voltage (800 µV maximum for the A version), the TSV62x is ideal for applications requiring precision. The device can operate at a power supply ranging from 1.5 to 5.5 V, and therefore suit battery-powered devices and extend their battery life. This product features an excellent speed/power consumption ratio, offering a 420 kHz gain bandwidth while consuming only 29 µA at a 5 V supply voltage. These operational amplifiers are unity gain stable for capacitive loads up to 100 pF. The device is internally adjusted to provide very narrow dispersion of AC and DC parameters, especially power consumption, product gain bandwidth, and slew rate. The TSV62x present high tolerance to ESD, sustaining 4 kV for the human body model. The device is offered in macropackages, SC70-6 and SOT23-6 for the TSV620 and SC70-5 and SOT23-5 for the TSV621. They are guaranteed for industrial temperature ranges from -40 °C to 125 °C. All these features make the TSV620, TSV620A, TSV621, and TSV621A ideal for sensor interfaces, battery-supplied and portable applications, as well as active filtering.

1 Absolute maximum ratings and operating conditions
Table 1. Absolute maximum ratings (AMR)
- All voltage values, except differential volt age are with respect to network ground terminal.
- Differential voltages are the non-inverting input termi nal with respect to the inverting input terminal.
- Vcc-Vin must not exceed 6 V.
- Input current must be limited by a resistor in series with the inputs.
- Vcc-SHDN must not exceed 6 V.
- Short-circuits can c ause excessive heating and destructive dissipation.
- Human body model: 100 pF discharged through a 1.5 k Ω resistor between two pins of the device, done for
all couples of pin combinations with other pins floating.
- Machine mode: a 200 pF capacitor is charged to the specified voltage, then discharged directly between
combinations with other pins floating.
- Charged device model: all pins plus package ar e charged together to the specified voltage and then
discharged directly to the ground. Table 2. Operating conditions

3.8 Macromodel
An accurate macromodel of the TSV620, TSV620A, TSV621, and TSV621A is available on STMicroelectronics’ web site at www.st.com. This model is a trade-off between accuracy and complexity (that is, time simulation) of the TSV62x operational amplifiers. It emulates the nominal performances of a typical device within the specified operating conditions mentioned in the datasheet. It helps to validate a design approach and to select the right operational amplifier, but it does not replace on-board measurements.
