INA826 Supply Instrumentation Amplifier

Texas Instruments precision, 200 µA supply current, 2.7 V to 36 V supply instrumentation amplifier

Texas Instruments INA826 Supply Instrumentation Amplifier Texas Instruments' INA826 is a low-cost instrumentation amplifier that offers extremely 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. It offers excellent stability over temperature, even at G>1, as a result of the low gain drift of only 35 ppm/°C (max).

The INA826 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. Using a rail-to-rail output, the INA826 is well-suited for low voltage operation from a 2.7 V single supply as well as dual supplies up to ±18 V.
