The Texas Instruments INA331IDGKT is a versatile instrumentation amplifier designed for low-power, single-supply operation. It features a wide supply voltage range from 2.5V to 5.5V and a broad operating temperature range of -55°C to 125°C.
Key electrical specifications include a low input offset voltage of ±500 µV maximum, a voltage gain adjustable from 5 to 1000, and a bandwidth of 2 MHz at minimum gain. The amplifier exhibits a high Common-Mode Rejection Ratio (CMRR) of 90 dB and a low input bias current of 0.01 nA maximum. Its gain error is ±0.1% maximum, with a gain nonlinearity of ±0.01% maximum.
The INA331IDGKT is suitable for applications such as industrial sensor amplifiers (bridge, RTD, thermocouple, position), physiological amplifiers (ECG, EEG, EMG), A/D converter signal conditioning, and differential line receivers. It is available in a VSSOP (DGK) 8-pin package with a package area of 14.7 mm².
Additional features include a quiescent current of 0.415 mA typical and a shutdown mode. The output swing is rail-to-rail, and input common-mode headroom is specified for both positive and negative supply rails.
