SBAS248B – DECEMBER 2001 – REVISED AUGUST 2007  
16-Bit, Single Channel  
DIGITAL-TO-ANALOG CONVERTER  
With Internal Reference and Parallel Interface  
DESCRIPTION  
FEATURES  
ꢀ LOW POWER: 150mW MAXIMUM  
The DAC7741 is a 16-bit Digital-to-Analog Converter (DAC)  
which provides 16 bits of monotonic performance over the  
specified operating temperature range and offers a +10V,  
low-drift internal reference. Designed for automatic test equip-  
ment and industrial process control applications, the DAC7741  
output swing can be configured in a ±10V, ±5V, or +10V  
range. The flexibility of the output configuration allows the  
DAC7741 to provide both unipolar and bipolar operation by  
pin strapping. The DAC7741 includes a high-speed output  
amplifier with a maximum settling time of 5µs to ±0.003%  
FSR for a 20V full-scale change and only consumes 100mW  
(typical) of power.  
ꢀ +10V INTERNAL REFERENCE  
ꢀ UNIPOLAR OR BIPOLAR OPERATION  
ꢀ SETTLING TIME: 5µs to ±0.003% FSR  
ꢀ 16-BIT MONOTONICITY, –40°C TO +85°C  
ꢀ ±10V, ±5V OR +10V CONFIGURABLE VOLTAGE  
OUTPUT  
ꢀ RESET TO MIN-SCALE OR MID-SCALE  
ꢀ DOUBLE-BUFFERED DATA INPUT  
ꢀ INPUT REGISTER DATA READBACK  
ꢀ SMALL LQFP-48 PACKAGE  
The DAC7741 features a standard 16-bit parallel interface with  
double buffering to allow asynchronous updates of the analog  
output and data read-back to support data integrity verification  
prior to an update. A user-programmable reset control allows  
the DAC output to reset to min-scale (0000H) or mid-scale  
(8000H) overriding the DAC register values. The DAC7741 is  
available in a LQFP-48 package and four performance grades  
specified to operate from 0°C to +70°C and –40°C to +85°C.
