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.
