GENERAL DESCRIPTION

The 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.

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.

The DAC8043’s 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.
