INA826S - 200 μA, 36V, Rail-to-Rail Out Instrumentation Amplifier with Shutdown

The INA826S device is a low-cost instrumentation amplifier that offers extremely lowpower consumption along with shutdown and operates over a very wide single- or dual-supply range. Asingle external resistor sets any gain from 1 to 1000. The device offers excellent stability overtemperature, even at G > 1, as a result of the low gain drift of only 35 ppm/°C (max).

The INA826S is optimized to provide excellent common-mode rejection ratio of over 100 dB(G = 10) over frequencies up to 5 kHz. At G = 1, the common-mode rejection ratio exceeds 84 dBacross the full input common-mode range from the negative supply all the way up to 1 V of thepositive supply. Using a rail-to-rail output, the INA826S is well-suited for low voltage operationfrom a 3-V single supply as well as dual supplies up to ±18 V.

Shutdown pins are provided to reduce supply current below 2 µA. Additional circuitryprotects the inputs against overvoltage of up to ±40 V beyond the power supplies by limiting theinput currents to less than 8 mA.

The INA826S is available in a 10-pin, 3-mm ×
3-mm VSON surface-mount package. The INA826S is specified over the –40°C to +125°Ctemperature range.
