INA826/7 Instrumentation Amplifiers

Texas Instruments' INA826/7 low-cost instrumentation amplifiers offer extremely-low power consumption

Image of Texas Instruments' INA826/7 Instrumentation Amplifiers Texas Instruments' INA826/7 are low-cost instrumentation amplifiers (INA) that offer extremely low power consumption and operate over a very wide single- or dual-supply range.

The INA826 has a single external resistor sets any gain from 1 to 1000. It offers excellent stability over temperature, even at G > 1, as a result of the low gain drift of only 35 ppm/°C (max). It is optimized to provide excellent common-mode rejection ratio of over 100 dB (G = 10) over frequencies up to 5 kHz. In G = 1, the common-mode rejection ratio exceeds 84 dB across the full input common-mode range from the negative supply all the way up to 1 V of the positive supply. 

The INA827 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. It 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.
