Texas Instruments  INA828IDR

The INA828 is a high-precision instrumentation amplifier that offers low powerconsumption and operates over a very wide single- or dual-supply range. A single external resistorsets any gain from 1 to 1000. The device offers excellent precision due to the use of newsuper-beta input transistors which provide exceptionally low input offset voltage, offset voltagedrift, input bias current, and input voltage and current noise. Additional circuitry protects theinputs against overvoltage up to ±40 V.

The INA828 is optimized to provide excellent common-mode rejection ratio. At G = 1, thecommon-mode rejection ratio exceeds 90 dB across the full input common-mode range. The device iswell-suited for low-voltage operation from a 5-V single supply as well as dual supplies up to ±18V. Finally, INA828 is available in an 8-pin SOIC package and specified over the –40°C to +125°Ctemperature range.
