AD5384 datasheet



The AD5384 is a complete single-supply, 40-channel, 14-bitdigital-to-analog converter (DAC) available in a 100-ball CSP_BGA package. All 40 channels have an on-chip output amplifier with rail-to-rail operation. The AD5384 includes an internal 1.25 V/2.5 V, 10 ppm/°C reference, an on-chip channel monitor function that multiplexes the analog outputs to a common MON_OUT pin for external monitoring, and an output amplifier boost mode that allows the amplifier slew rate to be optimized.

The AD5384 contains a serial interface compatible with SPI,QSPI, MICROWIRE, and DSP interface standards withinterface speeds in excess of 30 MHz and an I2C-compatible interface supporting 400 kHz data transfer rate. An input register followed by a DAC register provides double buffering, allowing the DAC outputs to be updated independently or simultaneously, using the LDAC input. Each channel has a programmable gain and offset adjust register letting the user
fully calibrate any DAC channel. Power consumption is typically 0.25 mA per channel with boost mode off.
