16-Bit, Quad Voltage Output  
DIGITAL-TO-ANALOG CONVERTER  
DESCRIPTION  
FEATURES  
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 8000H or to a zero-  
scale of 0000H. The DAC7644 can operate from a single  
+5V supply or from +5V and –5V supplies.  
LOW POWER: 10mW  
UNIPOLAR OR BIPOLAR OPERATION  
SETTLING TIME: 10µs to 0.003%  
15-BIT LINEARITY AND MONOTONICITY:  
–40°C to +85°C  
PROGRAMMABLE RESET TO MID-SCALE  
OR ZERO-SCALE  
DATA READBACK  
DOUBLE-BUFFERED DATA INPUTS  
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.
