AD5380

Data Sheet

GENERAL DESCRIPTION

The AD5380 is a complete, single-supply, 40-channel, 14-bit

denseDAC® available in a 100-lead LQFP package. All 40

channels have an on-chip output amplifier with rail-to-rail

operation. The AD5380 includes a programmable internal

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 AD5380 contains a double-buffered parallel

interface that 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

independently 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 with boost off.
