Digital-to-Analog Converters
with Serial Interface
CMOS LSI
The MC144110 and MC144111 are low–cost 6–bit D/A converters with serial
interface ports to provide communication with CMOS microprocessors and
microcomputers. The MC144110 contains six static D/A converters; the
MC144111 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 may
be directly interfaced to CMOS MPUs operating at 5 V.
