This document introduces the features and characteristics of AD5370 40-channel 16-bit serial input voltage output DAC.
The AD5370 is a 40‑channel, 16‑bit DAC offered in 64‑lead LFCSP and LQFP packages. It provides buffered voltage outputs with a nominal span of –4 V to +8 V and supports multiple independent output spans. The device includes a serial interface compatible with SPI, QSPI, Microwire, and DSP standards, and offers functions such as channel grouping, calibration, and thermal shutdown.
The datasheet lists detailed electrical specifications, timing characteristics, pin configurations, and ordering information for the AD5370. It also includes functional block diagrams, performance graphs, and mechanical dimensions for both package types.
