7 General Description
The MX7548 is a 12-bit CMOS, current output, multi-
plying digital-to-analog converter (DAC) with a versa-
tile interface for microprocessors using 8-bit busses.
The MX7548 accepts data into its input-registers in
two bytes in either left- or right-justified format, least
siigpificantlut_e or most significant byte first. Standard
WR and CSLSB or CSMSB inputs control the data
load operation. A separate LDAC input controls trans-
fer of data from the input register to the DAC register
allowing for simultaneous update of all DACs in
multi-DAC systems. A data override input forces the
DAC output to full-scale or zero-code without alter-
ing the contents of the input registers. This permits
the user to perform DAC calibration conveniently
without having to load calibration data into the DAC.
The MX7548 works with a single +5V, +12V or +15V
power supply, and the electrical characteristics are
specified at all of these supply voltages. All digital
inputs are TTL and HN-CMOS compatible with any
of these supply voltages.
Maxim MX7548 uses low tempco thin-film resistors
which are laser trimmed to -tc1/aLSB linearity and
better than t1LSB gain accuracy. The digital inputs
are designed with improved ESD protection and can
typically withstand over 5,000V of ESD voltages.
The MX7548 is supplied in 20-Iead narrow DIP, PLCC,
and Small Outline packages.
