GENERAL DESCRIPTION

The AD5381 is a complete, single-supply, 40-channel, 12-bit

denseDAC® availablein a 100-leadLQFP 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_OUTpin

for external monitoring, and an output amplifier boost mode,

which allowsoptimization of theamplifierslew rate. The AD5381

contains a double-buffered parallel interface featuring 20 ns WR

pulse width, an SPI-/QSPI-/MICROWIRE-/DSP-compatibleserial

interface with interface speeds in excess of 30 MHz, and an I2C-

compatible interface that supports a 400 kHzdata transfer rate.

An input register followed bya DACregister providesdouble

buffering, allowing the DACoutputsto be updated independ-

ently or simultaneously using the LDACinput.

Each channel has a programmablegain and offset adjust

nel. Power consumption is typically 0.25 mA/channel with

boost mode disabled.
