CMOS Low Cost, 10-Bit Multiplying DAC AD7533 FEATURES GENERAL DESCRIPTION Low cost 10-bit DAC The AD7533 is a low cost, 10-bit, 4-quadrant multiplying DAC Low cost AD7520 replacement manufactured using an advanced thin-film-on-monolithic- Linearity: LSB, 1 LSB, or 2 LSB CMOS wafer fabrication process. Low power dissipation Pin and function equivalent to the AD7520 industry standard, Full 4-quadrant multiplying DAC the AD7533 is recommended as a lower cost alternative for old CMOS/TTL direct interface AD7520 sockets or new 10-bit DAC designs. Latch free (protection Schottky not required) AD7533 application flexibility is demonstrated by its ability to Endpoint linearity interface to TTL or CMOS, operate on 5 V to 15 V power, and provide proper binary scaling for reference inputs of either APPLICATIONS positive or negative polarity.
