Overview
The AD5371BSTZ-REEL, produced by Analog Devices Inc., is a 40-channel, 14-bit, serial input, voltage output digital-to-analog converter (DAC). This device is available in an 80-lead LQFP package and is designed for high precision and flexibility in various applications. It features buffered voltage outputs with a span of 4 times the reference voltage, and each DAC can be independently trimmed for gain and offset. The device supports multiple output voltage spans and includes system calibration functions, channel grouping, and addressing features.
