This datasheet describes the AD5382, a 32-channel, 14-bit voltage output DAC with rail-to-rail output amplifiers and integrated reference voltage sources.
The AD5382 is a complete single-supply, 32-channel, 14-bit DAC available in a 100-lead LQFP package. All 32 channels feature an internal output amplifier operating in a rail-to-rail fashion. The device includes an internal reference voltage source selectable via software between 1.25 V and 2.5 V with a temperature coefficient of 10 ppm/°C. Internal channel monitoring functionality multiplexes analog outputs to a common MON_OUT pin for external monitoring, and the output amplifier boost mode optimizes the amplifier slew rate.
The AD5382 features a dual-buffer parallel interface with a WR pulse width of 20 ns and an interface speed exceeding 30 MHz, along with compatible SPI/QSPI/MICROWIRE/DSP serial interfaces. It supports data readback and I2C compatibility. User-programmable offset and gain adjustment registers allow for full calibration of any DAC channel. The device operates over a temperature range of -40°C to +85°C. This manual is written in Chinese.
