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

pin. Data in the DAC register is converted to an output current
by the D/A converter.
Consuming only 10 A 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
(40C to +85C) 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.
