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

input

pin. Data in the DAC register is converted to an output current

by the D/A converter.

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 a PDIP package, and the low profile 1.75 mm height SOIC-8

surface mount packages. The DAC8043AFRU is available for

ultra-compact applications in a thin 1.1 mm TSSOP-8 package.
