AD5390/AD5391/AD5392 are 8/16-channel, 3 V/5 V, serial input, single-supply, 12/14-bit voltage output DACs from Analog Devices. AD5390 is a 16-channel, 14-bit voltage output DAC, AD5391 is a 16-channel, 12-bit voltage output DAC, and AD5392 is an 8-channel, 14-bit voltage output DAC. These devices feature guaranteed monotonicity, output voltage range of ±1 V to +5 V, and a temperature range of -40°C to +85°C.
The AD5390, AD5391 and AD5392 are single‑supply DACs offering 8‑ or 16‑channel voltage output with 12‑ or 14‑bit resolution. They include on‑chip reference, channel monitor, boost mode, and programmable gain/offset. The devices support serial SPI®, QSPI™, Microwire™, DSP‑compatible and C‑compatible PC interfaces.
The datasheet lists electrical specifications, timing characteristics, pin configurations, and functional descriptions. It also provides package options, power‑down behavior, and revision history for design engineers.
