MC144110
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.

This device contains protection circuitry to
guard against damage due to high static
voltages or electric fields; however, it is ad-
vised that precautions be taken to avoid
application of voltage higher than maximum
rated voltages to this high–impedance circuit.
For proper operation it is recommended that
V in and V out be constrained to the range V SS

PROGRAM STEP
LINEARITY ERROR (integral linearity). A measure of how
straight a device’s transfer function is, it indicates the worst–case
deviation of linearity of the actual transfer function from the best–
fit straight line. It is normally specified in parts of an LSB.
