The AD5384 is a complete single-supply, 40-channel, 14-bit digital-to-analog converter (DAC) available in a 100-pin CSP_BGA package. All 40 channels feature an on-chip output amplifier that operates on rail-to-rail. The device has a built-in 1.25 V/2.5 V 10 ppm/°C reference source. On-chip channel monitoring multiplexes analog outputs to a common MON_OUT pin for external monitoring, and output amplifier boost mode optimizes amplifier slew rate. The AD5384 includes a serial interface compatible with SPI, QSPI, MICROWIRE, DSP interface standards with interface speeds greater than 30 MHz, and an I2C-compatible interface that supports 400 kHz data transfer rates. Input registers The rear DAC registers provide dual buffering, allowing each DAC output to be updated independently or simultaneously using the LDAC input. Each channel has programmable gain and offset adjustment registers that allow users to fully calibrate any DAC channel. When boost mode is disabled, the typical power consumption per channel is 0.25 mA.
