INTEGRATED CIRCUIT FOR CONDITIONING AND CONVERSION OF BI-DIRECTIONAL DISCRETE AND ANALOG SIGNALS

摘要

An integrated circuit chip (105) for interfacing a digital computer (103) to sensors (101) and controlled devices (107) can be configured to accept and provide a variety of analog and discrete input and output signals. The circuit includes a plurality of signal conditioning cells (111), a plurality of signal conversion cells (113), and input and output signal multiplexors.
