DESCRIPTION

The DAC7612 is a dual, 12-bit digital-to-analog converter

(DAC) with guaranteed 12-bit monotonicity

performance over the industrial temperature range. It

requires a single +5V supply and contains an input

shift register, latch, 2.435V reference, a dual DAC, and

high speed rail-to-rail output amplifiers. For a fullscale

step, each output will settle to 1 LSB within 7ms

while only consuming 3.7mW.

The synchronous serial interface is compatible with a

wide variety of DSPs and microcontrollers. Clock

(CLK), Serial Data In (SDI), Chip Select (CS) and

Load DACs (LOADDACS) comprise the serial interface.

The DAC7612 is available in an 8-lead SOIC package

and is fully specified over the industrial temperature

range of –40°C to +85°C.
