Overview
The AD7533JN, produced by Analog Devices Inc., is a low-cost, 10-bit, 4-quadrant multiplying Digital-to-Analog Converter (DAC). This component is manufactured using an advanced thin-film-on-monolithic-CMOS wafer fabrication process. It is pin and function equivalent to the industry-standard AD7520, making it a suitable lower-cost alternative for both existing AD7520 designs and new 10-bit DAC applications.
The AD7533JN offers flexibility in its ability to interface with TTL or CMOS logic, operate over a wide power supply range of 5 V to 15 V, and provide proper binary scaling for reference inputs of either positive or negative polarity.
