1 Overview

The INA851 is a high-precision instrumentation amplifier with differential outputs that is optimized to drive high-performance analog-to-digital converters (ADCs) with fully differential inputs. A single external resistor sets any gain from 0.2 V/V to 10,000 V/V. The device features super-beta input transistors from Texas Instruments, which provide ultra-low input offset voltage, offset drift, input bias current, input voltage noise, and current noise. For a full list of electrical characteristics for the INA851, see the INA851 Precision, Fully Differential Output, Instrumentation Amplifier data sheet.
