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.

Connect CAO to P1.6: See the MSPUM430.PDF file included with your software.

Connect CA1 to P1.7: See the MSPUM430.PDF file included with your software.
