AD7582: CMOS 12-Bit Successive Approximation A/D Converter

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 us per channel. An auto-zero cycle occurs at the start of each conversion resulting in very low system offset voltages, typically less than 100 uV. 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.
