DAC7744

DESCRIPTION

The DAC7744 is a 16-bit, quad voltage output digital­to-analog converter with guaranteed 16-bit monotonic
performance over the specified temperature range. It
accepts 16-bit parallel input data, has double-buffered
DAC input logic (allowing simultaneous update of all
DACs), and provides a readback mode of the internal
input registers. Programmable asynchronous reset
clears all registers to a mid-scale code of 8000H or to
a zero-scale of 0000H. The DAC7744 operates from
either a single +15V supply or from a +15V, –15V,
and +5V supply.

Low power and small size per DAC make the DAC7744
ideal for automatic test equipment, DAC-per-pin pro­grammers, data acquisition systems, and closed-loop
servo-control. The DAC7744 is available in a 48­lead SSOP package, and offers guaranteed specifica­tions over the –40°C to +85°C temperature range.

FEATURES

● LOW POWER: 200mW

● UNIPOLAR OR BIPOLAR OPERATION

● SINGLE-SUPPLY OUTPUT RANGE: +10V

● DOUBLE-BUFFERED DATA INPUTS

APPLICATIONS

● PROCESS CONTROL

● ATE PIN ELECTRONICS

● CLOSED-LOOP SERVO-CONTROL

ELECTROSTATIC
DISCHARGE SENSITIVITY

This integrated circuit can be damaged by ESD. Burr-Brown
recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling
and installation procedures can cause damage.

ESD damage can range from subtle performance degradation
to complete device failure. Precision integrated circuits may
be more susceptible to damage because very small parametric
changes could cause the device not to meet its published
specifications.

17 RSTSEL Reset Select. Determines the action of RST. If

HIGH, a RST command will set the DAC regis­ters to mid-scale. If LOW, a RST command will
set the DAC registers to zero.

18 RST Reset, Edge-Triggered. Depending on the state

of RSTSEL, the DAC Input and Output registers
are set to either mid-scale or zero.

19 LOADDACs DAC Output Registers Load Control. Rising edge
