INA827 - Texas Instruments

INA827 Instrumentation Amplifier

The INA827 is a low-cost instrumentation amplifier (INA) that offers extremely low power consumption and operates over a very wide single- or dual-supply range. The device is optimized for the lowest possible gain drift of only 1 ppm per degree Celsius in G = 5, which requires no external resistor. However, a single external resistor sets any gain from 5 to .
