Product Description

The AD8421BRZ is a Low Power High Speed Instrumentation Amplifier that is ideally suited for a broad spectrum of signal conditioning and data acquisition applications. The extremely low noise ultralow bias current instrumentation amplifier features extremely high CMRR allowing it to extract low level signals in the presence of high frequency common-mode noise over a wide temperature range. The AD8421 amplify high speed signals and excel in applications that require high channel count, multiplexed systems. Even at higher gains, the current feedback architecture maintains high performance. It has excellent distortion performance, making it suitable for use in demanding applications such as vibration analysis. This amplifier uses unique protection methods to ensure robust inputs while still maintaining very low noise. This protection allows input voltages up to 40V from the opposite supply rail without damage to the part.
