The AD5384 is a complete single supply, 40 channels, 14-bitDigital-to-analog converters(DAC) in a 100-pin CSP_BGA package. All 40 channels have an on-chip output amplifier that operates rail-to-rail. The device contains a 1.25 V/2.5 V, 10 ppm/°C reference. 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 contains a serial interface compatible with SPI, QSPI, MICROWIRE, DSP interface standards with interface speeds greater than 30 MHz and an I2C-compatible interface supporting 400 kHz data transfer rate. Input registers The post-DAC registers provide double buffering, allowing each DAC output to be updated independently or simultaneously using the LDAC input. Each channel has programmable gain and offset adjustment registers, allowing the user to fully calibrate any DAC channel. With boost mode disabled, typical power consumption is 0.25 mA per channel.
