Texas Instruments INA826 Precision Instrumentation Amplifiers
Texas Instruments INA826 Precision Instrumentation Amplifiers offer extremely low power consumption and operate over a very wide single or dual supply range. TI INA826 Instrumentation Amplifiers are optimized to provide an excellent common-mode rejection ratio of over 100dB (G=10) over frequencies up to 5kHz. The common-mode rejection ratio in G=1 exceeds 84dB across the full input common-mode range from the negative supply up to 1V of the positive supply. Using a rail-to-rail output, the TI INA826 is well-suited for low voltage operation from a 2.7V single supply as well as dual supplies up to ±18V. Additional circuitry protects the inputs against overvoltage of up to ±40V beyond the power supplies by limiting the input currents to less than 8mA. Texas Instruments INA826 Instrumentation Amplifiers are designed for use in a variety of applications, including industrial process controls, circuit breakers, battery tests, and ECG amplifiers.Features
