GENERAL DESCRIPTION
The AD7533 is a low cost, 10-bit, 4-quadrant multiplying DAC
manufactured using an advanced thin-film-on-monolithic-
CMOS wafer fabrication process.
Pin and function equivalent to the AD7520 industry standard,
the AD7533 is recommended as a lower cost alternative for old
AD7520 sockets or new 10-bit DAC designs.
AD7533 application flexibility is demonstrated by its ability to
interface to TTL or CMOS, operate on 5 V to 15 V power, and
provide proper binary scaling for reference inputs of either
positive or negative polarity.
