The unit connects Serial C Interface to an IBM-compatible personal computer running soft- Unipolar +4.096V or Bipolar -2.048V to +2.048V ware provided with the MAX186 EV kit. Both boards Input Ranges come fully assembled and tested. Internal Reference Voltage Using the EV system, the MAX186 input multiplexer can be software-configured in a variety of single-ended or dif- Low Supply-Current Shutdown Mode ferential modes with unipolar or bipolar input ranges.
