16-Bit, Quad Voltage Output

DIGITAL-TO-ANALOG CONVERTER

DAC7644

DESCRIPTION

The DAC7644 is a 16-bit, quad voltage output digital­to-analog converter with guaranteed 15-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 zero­scale of 0000H. The DAC7644 can operate from a single
+5V supply or from +5V and –5V supplies.

Low power and small size per DAC make the DAC7644
ideal for automatic test equipment, DAC-per-pin pro­grammers, data acquisition systems, and closed-loop
servo-control. The DAC7644 is available in a 48-lead
SSOP package and offers guaranteed specifications
over the –40°C to +85°C temperature range.

FEATURES

● LOW POWER: 10mW

● UNIPOLAR OR BIPOLAR OPERATION

● SETTLING TIME: 10µs to 0.003%

–40°C to +85°C

● PROGRAMMABLE RESET TO MID-SCALE

OR ZERO-SCALE

● DATA READBACK

● DOUBLE-BUFFERED DATA INPUTS

APPLICATIONS

● CLOSED-LOOP SERVO-CONTROL

● MOTOR CONTROL

● DATA ACQUISITION SYSTEMS

● DAC-PER-PIN PROGRAMMERS

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.

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, Rising Edge Triggered. Depending on the

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

19 LOADDACS DAC Output Registers Load Control. Rising edge

triggered.

20 R/W Enabled by the CS, Controls Data Read and Write
