Comparator

Target Category: MSP430

Sub-Target Category: ADC

Description: The Comparator block compares two voltages. It supports precision slope analog-to-digital conversions, supply voltage supervision, and monitoring of external analog signals. Features of the Comparator block include:

      Inverting and non-inverting terminal input multiplexer

      Software selectable RC-filter for the comparator output

      Output provided to Timer_A capture input

      Software control of the port input buffer

      Interrupt capability

      Selectable reference voltage generator

      Comparator and reference generator can be powered down

For more information on the Comparator block, see the MSPUM430.PDF file included with your software.

To compare voltages on a Delfino, F280x, or Piccolo, see Analog Comparator DAC block.

 

Choose VRef Pin: Selects the voltage reference pin.
