GENERAL DESCRIPTION

The AD5382 is a complete, single-supply, 32-channel, 14-bit denseDAC? available in a 100-lead LQFP package. All 32 channels have an on-chip output amplifier with rail-to-rail operation. The AD5382 includes an internal software-selectable 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 optimization of the amplifier slew rate.
