INA828 - Texas Instruments

INA828 Precision Instrumentation Amplifier

The INA828 is a high-precision instrumentation amplifier that 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 excellent precision due to the use of new super-beta input transistors which provide exceptionally low input offset voltage, offset vo.
