Data Sheet

AD5384

GENERAL DESCRIPTION

The AD5384 is a complete single-supply, 40-channel, 14-bit

digital-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 with

interface 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.
