DESCRIPTION

The DAC7800, DAC7801 and DAC7802 are mem-

bers of a new family of monolithic dual 12-bit CMOS

multiplying digital-to-analog converters. The digital

interface speed and the AC multiplying performance

are achieved by using an advanced CMOS process

optimized for data conversion circuits. High stability

on-chip resistors provide true 12-bit integral and dif-

ferential linearity over the wide industrial temperature

range of –40^oC to +85^oC.

DAC7802 has a single-buffered 12-bit data word in-

terface. Parallel data is loaded (edge triggered) into the

single D/A register for each D/A. DAC7802 is pack-

aged in a 24-pin 0.3" wide plastic DIP.

DAC A

DAC7800 features a serial interface capable of clock-

ing-in data at a rate of at least 10MHz. Serial data is

clocked (edge triggered) MSB first into a 24-bit shift

simultaneously as required by the application. An

asynchronous CLEAR control is provided for power-

on reset or system calibration functions. It is packaged

in a 16-pin 0.3" wide plastic DIP.

DAC7800

DAC7801 has a 2-byte (8 + 4) double-buffered

interface. Data is first loaded (level transferred) into

the input registers in two steps for each D/A. Then

both D/As are updated simultaneously. DAC7801 fea-

tures an asynchronous CLEAR control. DAC7801 is

packaged in a 24-pin 0.3" wide plastic DIP.
