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.
Consuming only 10
碌A(chǔ)
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
(鈥?0擄C to +85擄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.
