AD5382
GENERAL DESCRIPTION
speeds in excess of 30 MHz and an I2C compatible interface
that supports a 400 kHz data transfer rate.
The AD5382 is a complete, single-supply, 32-channel, 14-bit
DAC 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. The AD5382 contains a double-buffered parallel
An input register followed by a DAC register provides double
buffering, allowing the DAC outputs to be updated indepen-
dently or simultaneously using the
input.
LDAC
Each channel has a programmable gain and offset adjust
register that allows the user to fully calibrate any DAC channel.
Power consumption is typically 0.25 mA/channel when
operating with boost mode disabled.
