INA826AIDGKR Description
The INA826AIDGKR is a low-cost instrumentation amplifier that operates over a large single-supply or dual-supply range and consumes very little power. Any gain between 1 and 1000 can be set with a single external resistor. Because of the low gain drift of only 35 ppm/°C, the INA826AIDGKR has exceptional temperature stability, even at G > 1. (maximum).
Above frequencies up to 5 kHz, the INA826AIDGKR is tuned to give an excellent common-mode rejection ratio of over 100 dB (G = 10). At G = 1, the common-mode rejection ratio surpasses 84 dB across the whole input common-mode range, from negative to positive supply voltages of 1 V. The INA826AIDGKR is a fantastic choice for low-voltage operation from a 3-V single source, as well as dual supplies up to 18 V, thanks to its rail-to-rail output.
