T he DAC8043 is a high accuracy 12-bit CMOS multiplying  
DAC in a space-saving 8-pin mini-DIP package. Featuring serial  
data input, double buffering, and excellent analog performance,  
the DAC8043 is ideal for applications where PC board space is  
at a premium. Also, improved linearity and gain error performance  
permit reduced parts count through the elimination of trimming  
components. Separate input clock and load DAC control lines  
allow full user control of data loading and analog output.  
T he 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.

T he DAC8043s fast interface timing may reduce timing design  
considerations while minimizing microprocessor wait states. For  
applications requiring an asynchronous CLEAR function or more  
versatile microprocessor interface logic, refer to the PM-7543.

Operating from a single +5 V power supply, the DAC8043 is  
the ideal low power, small size, high performance solution to  
many application problems. It is available in plastic and cerdip  
packages that are compatible with auto-insertion equipment.
