INA819 High-Precision Instrumentation Amplifier

Texas Instruments INA819 High-Precision Instrumentation Amplifier offers low power consumption and operates over a very wide single or dual-supply range. A single external resistor sets any gain from 1 to 1000. The device offers high precision due to super-beta input transistors, which provide exceptionally low input offset voltage, offset voltage drift, input bias current, input voltage, and current noise. Additional circuitry protects the inputs against over-voltage up to ±60V.
