Description: AD7581CQ is a microprocessor compatible 8 bit, 8 channel, memory buffered, data-acquisition system on a monolithic CMOS chip. The AD7581CQ consists of an 8 bit successive approximation A/D converter, an 8 channel multiplexer, 8×8 dual-port RAM, three-state DATA drivers (for interface), address latches and microprocessor compatible control logic. The device interfaces directly to 8080, 8050, Z80, 6800 and other microprocessor systems. The successive approximation conversion takes place on a continuous, channel sequencing, base using microprocessor control signals for the clock. Data is automatically transferred to its proper location in the AD7581CQ at the end of each conversion.
