Overview
The AD7533KPZ is a low-cost, 10-bit, 4-quadrant multiplying Digital-to-Analog Converter (DAC) manufactured by Analog Devices Inc. It is produced using an advanced thin-film-on-monolithic-CMOS wafer fabrication process. This DAC is pin and function equivalent to the industry-standard AD7520, making it a suitable lower-cost alternative for both existing AD7520 sockets and new 10-bit DAC designs. The AD7533KPZ offers flexibility in its ability to interface with TTL or CMOS logic, operate over a power range of 5 V to 15 V, and provide proper binary scaling for reference inputs of either positive or negative polarity.
