INA827 Instrumentation Amplifier



Texas Instruments' wide supply range, rail-to-rail output INA with a minimum gain of 5


Texas Instruments INA827 Instrumentation Amplifier Texas Instruments' 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, requiring no external resistor. However, a single external resistor sets any gain from 5 to 1000.

The INA827 is optimized to provide excellent common-mode rejection ratio (CMRR) of over 88 dB (G = 5) over frequencies up to 5 kHz. In G = 5, CMRR exceeds 88 dB across the full input common-mode range from the negative supply all the way up to 1 V of the positive supply. Using a rail-to-rail output, the INA827 is well-suited for low-voltage operation from a 2.7 V single-supply, as well as dual supplies up to ±18 V.  INA827 Datasheet
