AD5383

GENERAL DESCRIPTION

The AD5383 is a complete, single-supply, 32-channel, 12-bit

denseDAC® available in a 100-lead LQFP package. All 32 channels

have an on-chip output amplifier with rail-to-rail operation.

The AD5383 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 AD5383

features

• Double-buffered parallel interface with a 20 ns WR

pulse width.

• SPI-/QSPI-/MICROWIRE-/DSP-compatible serial

interface with interface speeds in excess of 30 MHz.

• I2C-compatible interface that supports a 400 kHz data

transfer rate.

Data Sheet

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. With

boost off, power consumption is typically 0.25 mA/channel.
