AD8421ARZ Amplifier Description
The AD8421ARZ is a low-cost, low-power, ultralow bias current, high-speed instrumentation amplifier that is well-suited for a wide range of signal conditioning and data acquisition applications. This product has an extremely high CMRR, which enables it to extract low-level signals in the presence of high-frequency common-mode noise over a wide temperature range.
The AD8421ARZ's 10 MHz bandwidth, 35 V/s slew rate, and 0.6 s settling time to 0.001 percent (G = 10) enable it to amplify high-speed signals and excel in applications requiring multiplexed systems with a large channel count. The existing feedback architecture retains great performance even at larger gains; for example, at G = 100, the bandwidth is 2 MHz and the settling time is 0.8 s. Because of its exceptional distortion performance, the AD8421ARZ is well suited for use in demanding applications such as vibration analysis.
