- Monolithic Construction
The AD7582 is a medium speed, 4-channel 12-bit CMOS A/D converter which uses the successive approximation technique to provide a conversion time of 100 µs per channel. An auto-zero cycle occurs at the start of each conversion resulting in very low system offset voltages, typically less than 100 µV. The devices is designed for easy microprocessor interface using standard control signals; CS (decoded device address), RD (READ) and WR, (WRITE). The 4-channel multiplexer is controlled via address inputs A0 and A1.
Product Lifecycle Not Recommended for New Designs
This designates products ADI does not recommend broadly for new designs.
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. "Zero defects" for shipped products is always our goal.
