DAC7612
Dual, 12-Bit Serial Input
DIGITAL-TO-ANALOG CONVERTER
DESCRIPTION
The DAC7612 is a dual, 12-bit digital-to-analog con-
verter (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 full-
scale step, each output will settle to 1 LSB within 7
s
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 inter-
face.
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.
