The INA826 is a cost-effective instrumentation amplifier that offers extremely low powerconsumption and operates over a very wide single-supply or dual-supply range. A single externalresistor sets any gain from 1 to 1000. The device offers excellent stability over temperature, evenat G > 1, as a result of the low gain drift of only 35 ppm/°C (maximum).
The INA826 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 INA826 is a great choice for low-voltageoperation 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 thepower supplies by limiting the input currents to less than 8 mA.
The INA826 is available in 8-pin SOIC, VSSOP, and tiny 3-mm × 3-mm WSON surface-mountpackages. All versions are specified for the –40°C to +125°C temperature range.
