- _.. General Description
The MX7545 is a 12-bit CMOS multiplying di ttal-to-
analog converter (DAC) with internal data atches.
Input data is loaded as a_single _12;bit word and
latched under the control of CS and WR inputs. When
CS and WR are low, the input data latches are trans-
parent and the DAC output responds to any changes
in the digital input.
MX7545 works with a single+5V or +15V power supply.
Electrical characteristics are specified at both of these
supply voltages. With a HN supply. the digital inputs
are +5V TTL and CMOS compatible while high voltage
CMOS compatibility is maintained at +15V supply
range.
Maxim MX7545 uses low tempco thin-film resistors
which are laser-trimmed to result in linearity errors
that are ty ically ly', LSB and gain errors of maximum
i1 LSB ( grade).
The digital inputs are designed with improved protec-
tion against electrostatic discharge (ESD) damage
and can typically withstand to over 6,000V of ESD
voltages.
The MX7545 is supplied in 20-Iead narrow DIP and
Small Outline packages.
