Description 

The INA826AIDGKR 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. The device offers excellent stability over temperature, even at G > 1, as a result of the low gain drift of only 35 ppm/°C (max). 

The INA826AIDGKR 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 commonmode 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 INA826AIDGKR is well-suited for low voltage operation from a 3-V single supply as well as dual supplies up to ±18 V. 

Additional circuitry protects the inputs against overvoltage of up to ±40 V beyond the power supplies by limiting the input currents to less than 8 mA. 

The INA826AIDGKR is available in 8-pin SOIC, VSSOP, and tiny 3-mm × 3-mm WSON surface-mount packages. All versions are specified for the –40°C to +125°C temperature range.
