The INA851 is the industry’s first high-precision instrumentation amplifier with fully differential outputs. This device is optimized to drive inputs of modern high performance analog-to-digital converters (ADCs) with fully differential inputs. The INA851 operates over a very-wide, single-supply or dual-supply range. The output stage gain can be set to either 0.2 or to 1 by shorting or floating two pins. A single external resistor sets any input stage gain from 1 to 10,000.

Compared to other amplifiers in the same class, the INA851 offers very-low input bias current and low input-referred current noise as a result of super-beta input transistors. A state-of-the-art manufacturing process provides exceptionally low voltage noise, input offset voltage, and offset voltage drift. Additional circuitry protects the device inputs against overvoltage up to ±40 V beyond the power-supply voltages.The device outputs feature built-in clamping circuitry to protect the ADC or downstream device against overdrive damage.

The device is designed for operation from either an 8-V minimum single or ±4-V dual supply, and a maximum of 36-V single or ±18 V dual supply.
