Digital–to–Analog Converters
with Serial Interface
CMOS LSI
Legacy Device:
Motorola/Freescale MC144110, MC144111
The ML144110 and ML144111 are low–cost 6–bit D/A converters with
serial interface ports to provide communication with CMOS microproces-
sors and microcomputers. The ML144110 contains six static D/A convert-
ers; the ML144111 contains four converters.
Due to a unique feature of these DACs, the user is permitted easy scaling
of the analog outputs of a system. Over a 5 to 15 V supply range, these
DACs maybe directly interfaced to CMOS MPUs operating at 5 V
.
