GENERAL DESCRIPTION
The AD7545 is a monolithic 12-bit CMOS multiplying DAC
with onboard data latches. It is loaded by a single 12-bit wide
word and directly interfaces 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.
and applications with wide temperature variations.
The AD7545 can be used with any supply voltage from +5 V to
+15 V. With CMOS logic levels at the inputs the device dissi-
pates less than 0.5 mW for V
DD
= +5 V.
