Instrumentation Amplifier, INA818IDR, Texas Instruments

The INA818IDR is a high-precision instrumentation amplifier that offers low power consumption and operates over a very wide single-supply or dual supply range. A single external resistor sets any gain from 1 to 10000. The device offers high precision as a result of 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 overvoltage up to ±60 V. The INA818IDR is optimized to provide a high common mode rejection ratio. At G = 1, the common-mode rejection ratio exceeds 90 dB across the full input common-mode range. The device is designed for low voltage operation from a 4.5-V single supply, as well as dual supplies up to ±18 V.
