The AD5383 is a 32-channel, 3 V/5 V, single-supply, 12-bit, voltage output DAC.
The AD5383 is a complete, single‑supply, 32‑channel, 12‑bit DAC available in a 100‑lead LQFP package. All channels feature an on‑chip rail‑to‑rail output amplifier and an integrated 1.25 V/2.5 V reference with 10 ppm/°C temperature coefficient.
The device supports parallel, SPI/ QSPI/ MICROWIRE/ DSP‑compatible serial, and I²C‑compatible interfaces, offering flexible data rates up to 30 MHz. Optional boost mode improves slew rate, and each channel includes programmable gain and offset registers for calibration.
