12-Bit Quad Voltage Output  
DIGITAL-TO-ANALOG CONVERTER  
FEATURES  
DESCRIPTION  
The DAC7724 and DAC7725 are 12-bit quad voltage  
output digital-to-analog converters with guaranteed  
12-bit monotonic performance over the specified tem-  
perature range. They accept 12-bit parallel input data,  
have double-buffered DAC input logic (allowing simul-  
taneous update of all DACs), and provide a readback  
mode of the internal input registers. An asynchronous  
reset clears all registers to a mid-scale code of 800H  
(DAC7724) or to a zero-scale of 000H (DAC7725). The  
DAC7724 and DAC7725 can operate from a single  
+15V supply, or from +15V and –15V supplies.  
LOW POWER: 250mW max  
SINGLE SUPPLY OUTPUT RANGE: +10V  
DUAL SUPPLY OUTPUT RANGE: ±10V  
SETTLING TIME: 10µs to 0.012%  
12-BIT LINEARITY AND MONOTONICITY:  
–40°C to +85°C  
RESET TO MID-SCALE (DAC7724) OR  
ZERO-SCALE (DAC7725)  
DATA READBACK  
DOUBLE-BUFFERED DATA INPUTS  
Low power and small size per DAC make the DAC7724  
and DAC7725 ideal for automatic test equipment,  
DAC-per-pin programmers, data acquisition systems,  
and closed-loop servo-control. The DAC7724 and  
DAC7725 are available in a PLCC-28 or a SO-28  
package, and offer guaranteed specifications over the  
–40°C to +85°C temperature range.
