MX7245JN
Complete, 12-Bit Voltage-Output DACs
19-3987; Rev 0; 11/91
General Description
The MX7245/MX7248 are complete, 12-bit digital-to-
analog converters (DACs) that include an internal voltage
reference and a voltage-output amplifier. The
MX7245/MX7248 are pin and electrically compatible with
Analog Devices' AD7245/AD7248.
The MX7245/MX7248 have double-buftered logic inter-
faces that are easily interfaced to microprocessors (PPs).
Data is transferred into the Input register from a 12-bit-
wide data bus (MX7245) for 16-bit pPs, or in a right-jus-
tified (8+4)-bit format (MX7248) for 8- and 16-bit WPS. All
logic signals are level triggered and are TTL and CMOS
compatible. The timing specifications ensure com-
patiblity with common WPS.
The DACs are specified and tested for both dual- and
single-supply operation. Usable supplies range from
single +12V to dual i15V.
Internal gain-setting resistors allow three output voltage
ranges: 0V to +5V and 0V to +10V can be generated
using either single or dual supplies. With dual supplies,
an additional output range of eN is available. The output
amplifier drives 2m loads to +10V.
See MAX507/MAX508 data sheet for detailed description.
