Digital-to-Analog Converters with Serial Interface CMOS LSI

Introduction

The MC144110 and MC144111 are low-cost 6-bit D/A converters with serial interface ports to provide communication with CMOSmicroprocessors 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.
