Microcomputer Analog I/O Systems OEM BURR-BROWN 

A 31-CHANNEL ANALOG INPUT, 2-CHANNEL OUTPUT SYSTEM COMPATIBLE WITH INTEL SBC80, INTELLEC MDS AND NATIONAL BLC-80 MICROCOMPUTERS

The MP8418 series of analog I/O peripherals are electrically and mechanically compatible with and interface directly to Intel’s Multibus and other microcomputers of similar configuration.  These analog systems are treated as memory by the CPU.

 

The analog input portion of the MP8418 includes:  over-voltage protection to 26 VDC; provision for up to eight 4mA to 20mA inputs; an analog multiplexer; resistor-programmed instrumentation amplifier or, a software-programmable amplifier (gain of 1 to 1024); sample/hold amplifier and; a 12-bit A/D converter.  An optional analog output system is included on the same board.  It consists of two 12-bit D/A converters with double buffered inputs to minimize glitches, and control logic.

MP8418 is a 15 channel differential (user-strapable as 31 channel single-ended) analog input system.  With one expander board the system can be expanded to 63 differential channels (strapable as 127 single-ended channels).  Another input channel is grounded on the board so that it may be used as ground reference for automatic calibration.

 

Gains of 1 to 1024 are software-selectable for the programmable amplifiers and the gain for each channel (up to 127 channels) may be stored in an on-board RAM if desired.  The proper gain for each channel is then selected automatically by the MP8418.
