Overview
The AD5372BSTZ is a 32-channel, 16-bit digital-to-analog converter (DAC) produced by Analog Devices Inc. This device is housed in a 64-lead Low Profile Quad Flat Package (LQFP) and offers a high degree of flexibility and precision. It features buffered voltage outputs with a nominal span of 4 times the reference voltage, and each DAC can be independently trimmed for gain and offset to remove errors. The device is divided into four groups of eight DACs, with two offset DACs allowing the output range of the groups to be adjusted. The AD5372BSTZ is designed for a wide range of applications, including level setting in automatic test equipment, variable optical attenuators, optical switches, industrial control systems, and instrumentation.
