AD8421ARZ (ANALOG DEVICES)

The AD8421ARZ is a high speed Instrumentation Amplifier, ideally suited for a broad spectrum of signal conditioning and data acquisition applications. This 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. It has excellent distortion performance, making it suitable for use in demanding applications such as vibration analysis. It delivers 3nV/vHz input voltage noise and 200fA/vHz current noise with only 2mA quiescent current, making it an ideal choice for measuring low level signals. For applications with high source impedance, this employs innovative process technology and design techniques to provide noise performance that is limited only by the sensor. Uses unique protection method 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.
