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.
The AD5382 contains a double-buffered parallel interface,
which features a 20 ns WR pulse width, an SPI-, QSPI-,
MICROWIRE-, DSP-compatible serial interface with
interface speeds in excess of 30 MHz and an I2C-compatible
interface that supports a 400 kHz data transfer rate.
An input register followed by a DAC register provides double
buffering, allowing the DAC outputs to be updated indepen-
dently or simultaneously using the LDAC input.
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.
