Overview
The AD5371BSTZ from Analog Devices Inc. is a 40-channel, 14-bit, serial input, voltage output Digital-to-Analog Converter (DAC). This device is available in either an 80-lead LQFP or a 100-ball CSP_BGA package. It features buffered voltage outputs with a span of 4 times the reference voltage, providing high precision and flexibility. The AD5371 is designed for applications requiring multiple DAC channels with independent gain and offset adjustments, ensuring accurate calibration and error removal.
