Data Sheet
AD5381
GENERALDESCRIPTION
The AD5381 is a complete, single-supply, 40-channel, 12-bit
denseDAC® availablein a 100-lead LQFP package. All 40 channels
have an on-chip outputamplifier with rail-to-rail operation.
The AD5381 includes a programmableinternal 1.25 V/2.5 V,
10 ppm/°C reference, an on-chip channel monitorfunction that
multiplexes the analog outputs to a common MON_OUT pin
for external monitoring, and an output amplifier boost mode,
which allowsoptimization of the amplifierslew rate. The AD5381
An input register followed bya DACregister providesdouble
buffering, allowing the DACoutputsto be updated independ-
ently or simultaneously using the
input.
LDAC
Each channelhas a programmablegain and offset adjust
register that allows the userto fully calibrate any DACchan-
nel. Power consumption is typically 0.25mA/channel with
boost mode disabled.
contains a double-buffered parallelinterface featuring 20 ns
WR
pulse width, an SPI-/QSPI-/MICROWIRE-/DSP-compatible serial
interface with interface speeds in excess of 30MHz, and an I2C-
compatible interface that supports a 400kHzdata transfer rate.
