DESCRIPTION

The DAC7800, DAC7801 and DAC7802 are members of a

new family of monolithic dual 12-bit CMOS multiplying Digi-

tal-to-Analog Converters (DACs). 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 differential linearity over the wide industrial

temperature range of –40°C to +85°C.

DAC7802 has a single-buffered 12-bit data word interface.

Parallel data is loaded (edge triggered) into the single DAC

wide plastic DIP.

12-Bit Interface

R_{FB A}

I_{OUT A}

V_{REF A}

DAC7800 features a serial interface capable of clocking-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 DAC separately or simultaneously as

required by the application. An asynchronous CLEAR control

is provided for power-on reset or system calibration func-

tions. 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 DAC. Then both DACs are updated

simultaneously. DAC7801 features an asynchronous CLEAR

control. DAC7801 is packaged in a 24-pin 0.3" wide plastic

DIP.
