ABSTRACT:
A unit for providing an interface between analog input signals and a digital data processing system bus includes a plurality of analog input channels, sample-and-hold circuits, and an analog-to-digital converter. An optical isolation circuit couples the output of the analog-to-digital converter to a dual-port RAM. The gain of each analog input channel is programmable, as is the address of each input channel in the RAM. Thus the channels can be read in any desired order, and different input voltage ranges can be programmed for each channel. The RAM can be read by an external data processing system via a digital system bus.
