The INA826AIDGKR is a precision low power Instrumentation Amplifier that offers extremely low power consumption and operates over a very wide single 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 35ppm/°C maximum. The INA826 is optimized to provide excellent common-mode rejection ratio of over 100dB (G=10) over frequencies up to 5kHz. In G=1, the common-mode rejection ratio exceeds 84dB across the full input common-mode range from the negative supply all the way up to 1V of the positive supply. Using a rail-to-rail output, the amplifier is well-suited for low voltage operation from a 2.7V single supply. Additional circuitry protects the inputs against overvoltage of up to ±40V beyond the power supplies by limiting the input currents to less than 8mA.
