## Description

The Texas Instruments INA321EA/2K5 is a micropower instrumentation amplifier designed for single-supply operation. It offers a low quiescent current of 40µA per channel and a shutdown mode that reduces current to less than 1µA. This amplifier supports a wide supply voltage range from 2.5V to 5.5V.

Key electrical specifications include a low input offset voltage of ±500µV maximum, a wide voltage gain range from 5V/V to 1000V/V, and a bandwidth of 0.5MHz at minimum gain. The device boasts high gain accuracy and common-mode rejection ratio (CMRR).

The INA321EA/2K5 features rail-to-rail output swing, providing maximum dynamic range. It operates across a wide temperature range of -55°C to 125°C. The component is available in a VSSOP (DGK) 8-pin package, suitable for surface mounting.

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