AD5382 is a 32-channel, 3 V/5 V, single-supply, 14-bit, voltage output DAC from Analog Devices. It features guaranteed monotonic INL error of ±4 LSB max; an on-chip 1.25 V/2.5 V, 10 ppm/°C reference; a temperature range of –40°C to +85°C; a rail-to-rail output amplifier; a power-down mode; a 100-lead LQFP (14 mm × 14 mm) package; and parallel serial (SPI®-/QSPI™-/MICROWIRE™-/DSP-compatible, featuring data readback) and I2C®-compatible user interfaces.
The AD5382 is a complete, single‑supply, 32‑channel, 14‑bit DAC available in a 100‑lead LQFP package. Each channel includes an on‑chip output amplifier with rail‑to‑rail operation and a selectable 1.25 V/2.5 V reference. The device supports parallel, SPI, QSPI, MICROWIRE, DSP‑compatible, and I²C‑compatible serial interfaces, allowing flexible integration.
Key features include a guaranteed monotonic INL error of ±4 LSB, programmable gain and offset per channel, a channel‑monitor function, boost mode for higher slew rate, and power‑down mode. The DAC operates over a temperature range of –40 °C to +85 °C and offers low power consumption, making it suitable for instrumentation, optical attenuators, MEMS control, and other precision applications.
