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 –40oC to +85oC.
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
register and then latched into each D/A separately or
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.
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.
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.
