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.
