DIGITAL-TO-ANALOG CONVERTER
FEATURES DESCRIPTION в—Џ LOW POWER: 10mW
в—Џ UNIPOLAR OR BIPOLAR OPERATION 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. ● SETTLING TIME: 10µs to 0.003%
