Product Summary

The AD7578KN is a medium speed, monolithic 12-bit CMOS A/D converter which uses the successive approximation technique to provide a conversion time of 100us. An auto-zero cycle occusrs at the start of each conversion resulting in very low system offset votlages, typically less than 100uV. The AD7578KN is designed for easy microprocessor interfacing using standard control signals, CS, RD, and WR.
