DAC7644
16-Bit, Quad Voltage Output
DIGITAL-TO-ANALOG CONVERTER
DAC7644
DESCRIPTION
The DAC7644 is a 16-bit, quad voltage output digital-
to-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 8000
H or to a zero-
scale of 0000
H. 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 pro-
grammers, 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.
