Description for the INA819

The INA819 is a high-precision instrumentation amplifier that offers low powerconsumption and operates over a very wide single-supply or dual-supply range. A single externalresistor sets any gain from 1 to 10,000. The device offers high precision as a result of super-betainput transistors, which provide exceptionally low input offset voltage, offset voltage drift,input bias current, input voltage, and current noise. Additional circuitry protects the inputsagainst overvoltage up to ±60 V.

The INA819 is optimized to provide a high common-mode rejection ratio. At G = 1, thecommon-mode rejection ratio exceeds 90 dB across the full input common-mode range. The device isdesigned for low-voltage operation from a 4.5-V single supply, as well as dual supplies up to ±18V.

The INA819 is available in 8-pin SOIC, VSSOP, and WSON packages, and is specified overthe –40°C to +125°C temperature range.
