GENERAL DESCRIPTION

The AD5452W is a CMOS 12-bit current output digital-to-analog

converter. This device operates from a 2.5 V to 5.5 V power supply,

making it suited to several applications, including battery-

powered applications.

The applied external reference input voltage (V_REF) determines

the full-scale output current. This part can handle 10 V inputs

on the reference, despite operating from a single-supply power

supply of 2.5 V to 5.5 V. An integrated feedback resistor (R_FB)

provides temperature tracking and full-scale voltage output

when combined with an external current-to-voltage precision

amplifier.

As a result of manufacture on a CMOS submicron process, this

DAC offers excellent four-quadrant multiplication characteris-

tics of up to 12 MHz.

The AD5452W DAC is available in an 8-lead MSOP package.

This DAC utilizes a double-buffered, 3-wire serial interface that

is compatible with SPI, QSPI™, MICROWIRE™, and most DSP

interface standards. Upon power-up, the internal shift register

and latches are filled with 0s, and the DAC output is at zero scale.
