Description

The TPA551x is the nano-power, zero-drift amplifier with a maximum 30-μV low-offset voltage and stable frequency response for the high-precision sensing application that also requires low standby power. The TPA551x devices provide rail-to-rail input and output. The devices have excellent AC performance with 9-kHz bandwidth, 3-V/ms slew rate while only drawing 650-nA quiescent current per amplifier. The TPA5511 and TPA5511U (1-ch version) are offered in the SOT23-5 and SOT353 (SC70-5) packages. The TPA5512 (2-ch version) is available in the SOP8, TSSOP8, MSOP8, DFN1.5X1.5-8, and DFN2X2-8 packages. All versions can be operated over the industrial temperature range from −40°C to +125°C.

Exposure to any Absolute Maximum Rating condition for extended periods may affect device reliability and lifetime. (2) The inputs are protected by ESD protection diodes to the negative power supply. If the input extends more than 300 mV beyond the negative power supply, the input current should be limited to less than 10 mA. (3) A heat sink may be required to keep the junction temperature below the absolute maximum. This depends on the power supply voltage and how many amplifiers are shorted. Thermal resistance varies with the amount of PC board metal connected to the package. The specified values are for short traces connected to the leads.

presented in Typical Performance Characteristics. Figure 20. Functional Block Diagram temperature range and over their operating lifetime. Flicker noise, as known as 1/f noise, is inherent in semiconductor devices and increases as the frequency decreases. range compared to the standard amplifier.

The chopping technique can be used in the amplifier design due to the internal notch filter. Although the chopping-related voltage ripple is suppressed, a higher noise spectrum exists at the chopping frequency and its harmonics due to residual ripple. The devices set the chopping frequency to 1 kHz. If the frequency of the input signal is close to the chopping frequency, the signal may be interfered with by the residue ripple. To suppress the noise at the chopping frequency, it is recommended that a post filter be placed at the output of the amplifier. Rail-to-Rail Input The input common-mode voltage range of the devices extends to the supply rails. This performance is achieved with a complementary input stage: a PMOS input differential pair in parallel with an NMOS input differential pair. Rail-to-Rail Output The devices deliver rail-to-rail output swing capability with a class-AB output stage. Different load conditions change the ability of the amplifier to swing close to the rails.
