A
The DAC8043A is an improved high accuracy 12-bit multiply-  
ing digital-to-analog converter in space-saving 8-lead packages.  
Featuring serial input, double buffering and excellent analog  
performance, the DAC8043A is ideal for applications where PC  
board space is at a premium. Improved linearity and gain error  
performance permit reduced parts count through the elimina-  
tion of trimming components. Separate input clock and load  
DAC control lines allow full user control of data loading and  
analog output.

The circuit consists of a 12-bit serial-in/parallel-out shift regis-  
ter, a 12-bit DAC register, a 12-bit CMOS DAC and control  
logic. Serial data is clocked into the input register on the rising  
edge of the CLOCK pulse. When the new data word has been  
clocked in, it is loaded into the DAC register with the LD input  
pin. Data in the DAC register is converted to an output current  
by the D/A converter.

CODE  
Figure 1. Integral Nonlinearity Error vs. Code  
Consuming only 10 µA from a single +5 V power supply, the  
DAC8043A is the ideal low power, small size, high performance  
solution to many application problems.  
The DAC8043A is specified over the extended industrial  
(–40°C to +85°C) temperature range. DAC8043A is available  
in plastic DIP, and the low profile 1.75 mm height SO-8 surface  
mount packages. The DAC8043AFRU is available for ultra-  
compact applications in a thin 1.1 mm TSSOP-8 package.
