Overview
The INA827AIDGK from Texas Instruments is a wide supply range, rail-to-rail output instrumentation amplifier. This device is designed to amplify the difference between two input signal voltages while rejecting any signals that are common to both inputs. It maintains DC precision and gain accuracy even in noisy environments and where large common-mode signals are present. The INA827AIDGK is optimized for low power consumption, operating with a typical supply current of 200 μA, and is available in an 8-pin VSSOP package.
