INA827AIDGKR

Description

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 1000.

Features

• Eliminates Errors from External Resistors at Gain of 5
• Common-Mode Range Goes Below Negative Supply
