Precise and reliable instrumentation amplifier for various industries

INA826AIDGK General Description

One of the key features of the INA826 is its exceptional common-mode rejection ratio of over 100 dB at a gain of 10, ensuring accurate signal processing even in noisy environments. At a gain of 1, the common-mode rejection ratio remains impressive at 84 dB across the full input common-mode range. Additionally, the amplifier offers rail-to-rail output, making it suitable for low-voltage applications with a single supply voltage as low as 3V, as well as dual supplies up to ±18V
