The AD8422ARZ with Instrumentation Amplifiers 330 uA Rail to Rail manufactured by Analog Devices is a dual operational amplifier that provides high common-mode rejection and wide bandwidth in a small 1.4 mm × 2 mm size. It is also rail-to-rail input and output, making it suitable for small-signal conditioning applications such as low-end audio, sensor signal conditioning, motion detectors, and security systems. With a wide supply voltage range from 2.7 V to 32 V, the AD8422ARZ provides a low input bias current of 330 µA, lower than any other instrumentation amplifier. The amplifier also provides up to 1.5 Mbps bandwidths with 500 V/µs slew rate and excellent PSRR of 92 dB. The AD8422ARZ offers enhanced input protection, superb dc accuracy, and small form and size, making it ideal for demanding portable and precision industrial control applications.
