GENERAL DESCRIPTION
The MP7533 is a low cost, 10-bit multiplying Digital-to-Analog
Converter. This device uses EXAR’s patented advanced thin
film resistor and CMOS technologies, providing up to 10-bit ac-
curacies with TTL/CMOS compatibility.
Pin and functional equivalent to the industry standard
MP7520, the MP7533 is recommended as a lower cost alterna-
tive for old MP7520 sockets or new 10-bit DAC designs.
The MP7533 applications include: digital-to-analog multipli-
cation, CRT character generation, programmable power sup-
plies, digitally controlled gain circuits, etc.
