DAC7634  
SBAS134AJULY 2004REVISED AUGUST 2004  
16-BIT, QUAD VOLTAGE OUTPUT  
DIGITAL-TO-ANALOG CONVERTER  
FEATURES  
DESCRIPTION  
Low Power: 10 mW  
The DAC7634 is a 16-bit, quad voltage output, digital-  
to-analog converter with specified 15-bit monotonic  
performance over the specified temperature range. It  
accepts 24-bit serial input data, has double-buffered  
DAC input logic (allowing simultaneous update of all  
Unipolar or Bipolar Operation  
Settling Time: 10 µs to 0.003%  
15-Bit Linearity and Monotonicity:  
–40°C to 85°C  
DACs), and provides  
a serial data output for  
daisy-chaining multiple DACs. Programmable asyn-  
chronous reset clears all registers to a mid-scale  
code of 8000H or to a zero-scale of 0000H. The  
DAC7634 can operate from a single 5-V supply or  
from 5-V and –5 V supplies.  
Programmable Reset to Mid-Scale  
or Zero-Scale  
Double-Buffered Data Inputs  
APPLICATIONS  
Low power and small size per DAC make the  
DAC7634 ideal for automatic test equipment,  
DAC-per-pin programmers, data acquisition systems,  
and closed-loop servo-control. The DAC7634 is avail-  
able in a 48-lead SSOP package and offers specifi-  
cations over the –40°C to 85°C temperature range.
