AD5370 is a 40-channel, 16-bit, serial input, voltage output DAC with the following features:
The AD5370 is a 40‑channel, 16‑bit digital‑to‑analog converter offered in 64‑lead LFCSP and LQFP packages. It provides buffered voltage outputs with a span up to four times the reference voltage and supports independent gain and offset trimming for each channel. The device includes a high‑speed serial interface compatible with SPI, QSPI, Microwire and DSP standards, capable of clock speeds up to 50 MHz.
Key features include guaranteed monotonicity to 16 bits, multiple independent output spans, a thermal shutdown function, and a flexible grouping architecture that allows channel grouping and addressing. Detailed specifications cover accuracy, power requirements, timing characteristics, and package dimensions, enabling designers to integrate the AD5370 into test equipment, optical attenuators, industrial control systems and other instrumentation applications.
