INA331AIDGKT Description

Short technical summary and product information.

The Texas Instruments INA331AIDGKT is a cost-optimized, low-power, single-supply CMOS instrumentation amplifier designed for high gain accuracy. It supports a supply voltage range from 2.5V to 5.5V and offers a voltage gain from 5 V/V up to 1000 V/V.

 

Key electrical specifications include a low input offset voltage of ±500 µV (max), a high Common-Mode Rejection Ratio (CMRR) of 90 dB, and a low input bias current of 0.01 nA (max). The amplifier operates with a quiescent current of 0.415 mA (typ) and features a bandwidth of 2 MHz at minimum gain.

 

This instrumentation amplifier is suitable for a wide operating temperature range of -55°C to 125°C. It is available in a VSSOP (DGK) package, measuring 14.7 mm² (3 mm × 4.9 mm), and is designed for surface mount applications.

 

Applications include industrial sensor amplifiers, physiological amplifiers, A/D converter signal conditioning, and differential line receivers.
