COMPARATOR MODULE

Comparators are used to interface analog circuits to a

digital circuit by comparing two analog voltages and

providing a digital indication of their relative magnitudes.

Comparators are very useful mixed-signal building

blocks because they provide analog functionality

independent

program

execution.

The

analog

comparator module includes the following features:

• Independent comparator control

• Programmable input selection

• Comparator output is available internally/externally

• Programmable output polarity

• Interrupt-on-change

• Wake-up from Sleep

• Programmable Speed/Power optimization

•PWM shutdown

• Programmable and Fixed Voltage Reference

Comparator Overview

A single comparator is shown in Figure 15-1 along with

the relationship between the analog input levels and

the digital output. When the analog voltage at VIN+ is

less than the analog voltage at VIN-, the output of the

comparator is a digital low level. When the analog

voltage at VIN+ is greater than the analog voltage at

VIN-, the output of the comparator is a digital high level.

Note:

The black areas of the output of the

comparator represents the uncertainty

due to input offsets and response time.
