AD8421ARMZ规格书详情
GENERAL DESCRIPTION
The AD8421is a low cost, low power, extremely low noise, ultra low bias current, high speed instrumentation amplifier that is ideally suited for a broad spectrum of signal conditioning and data acquisition applications. This product 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 10 MHz bandwidth, 35 V/μs slew rate, and 0.6 μs settling time to 0.001 (G = 10) allow the AD8421to 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; for example, at G = 100, the bandwidth is 2 MHz and the settling time is 0.8 μs. The
AD8421has excellent distortion performance, making it suitable for use in demanding applications such as vibration analysis.
