GENERAL DESCRIPTION

The MP75L45 is a 12-bit CMOS multiplying Digital-to-Analog

Converter with on-board data latches. It is loaded by a single

12-bit wide word and interfaces directly to most 12- and 16-bit

bus systems. Data is loaded into the input latches under the

control of the CS and WR inputs; tying these control inputs low

makes the input latches transparent, allowing direct unbuffered

operation of the DAC.

The MP75L45 is particularly suitable for single supply opera-

tion and applications with wide temperature variations.

Specified for operation over the commercial / industrial (–40

to +85°C) temperature range, the MP75L45 is available in Plas-

tic dual-in-line (PDIP), Surface Mount (SOIC), and Shrunk Small

(SSOP) outline packages.
