Double-Buffered D to A Converters

General Description

The DAC100678 are advanced CMOSSi-Cr 10- 9- and

8-bit accurate multiplying DACs which are designed to inter-

face directly with the 8080 8048 8085 Z-80 and other pop-

ular microprocessors These DACs appear as a memory lo-

cation or an IO port to the mP and no interfacing logic is

needed

These devices combined with an external amplifier and

voltage reference can be used as standard DA converters

and they are very attractive for multiplying applications

(such as digitally controlled gain blocks) since their linearity

error is essentially independent of the voltage reference

They become equally attractive in audio signal processing

equipment as audio gain controls or as programmable at-

tenuators which marry high quality audio signal processing

to digitally based systems under microprocessor control

All of these DACs are double buffered They can load all 10

bits or two 8-bit bytes and the data format is left justified

The analog section of these DACs is essentially the same

as that of the DAC1020

The DAC1006 series are the 10-bit members of a family of

microprocessor-compatible DAC’s (MICRO-DACTM’s) For

applications requiring other resolutions the DAC0830 series

(8 bits) and the DAC1208 and DAC1230 (12 bits) are avail-

able alternatives
