Description
AD8397ARZ-REEL7 is Analog Devices’ high-performance, low-distortion, fully differential amplifier. ARZ denotes an 8-pin RoHS-compliant MSOP package; REEL7 means parts are shipped on a 7-inch reel for automated assembly. The AD8397 supports single-ended-to-differential or differential-to-differential operation, delivering clean differential outputs with controlled common-mode. It offers high slew rate, wide bandwidth, low distortion, and good PSRR, making it suitable for driving ADCs/DACs, instrumentation, and high-speed interfaces. Typical usage: set gain with external feedback resistors, power from V+ and V– (or single-supply with bias), and include proper input/output decoupling. For exact electrical characteristics (bandwidth, slew rate, noise, output swing) and pinout details, consult the AD8397 datasheet and procurement spec. The reel packaging supports automatic tape-and-reel handling.
Equivalent
There isn’t an exact one-for-one cross for AD8397ARZ-REEL7. Closest cross-refs from other vendors include TI THS4521/THS4522 (high-speed differential amps) and Analog Devices/Linear Technology parts such as AD8275/AD8279 and LTC6409 (high-speed differential amps). Exact match depends on GBW, slew rate, input noise, supply range, and output CM range. Use a distributor’s cross-reference or ADI’s cross-reference tool with your specs to identify the best exact alternatives.
