AD5372/AD5373 is a 32-channel, 16/14-bit, serial input, voltage output DAC from Analog Devices.
The AD5372 and AD5373 are 32‑channel, 16‑/14‑bit voltage‑output DACs packaged in a 64‑lead LQFP. They provide buffered outputs with a nominal span of four times the reference voltage and support independent gain and offset trimming for each channel. The devices include a high‑speed serial interface compatible with SPI, QSPI, Microwire, and DSP standards, capable of clock speeds up to 50 MHz.
Typical applications include automatic test equipment, optical attenuators, industrial control systems, and instrumentation. The datasheet includes detailed specifications, timing diagrams, pin configurations, power‑supply decoupling guidelines, and example interfacing circuits for DSPs and microcontrollers.
