analog comparator

analog comparator

[′an·əl‚äg kəm′par·əd·ər]
(electronics)
A comparator that checks digital values to determine whether they are within predetermined upper and lower limits.
A comparator that produces high and low digital output signals when the sum of two analog voltages is positive and negative, respectively.

The MSP430C1101 includes 1 kB of ROM, 128 bytes of RAM, a watchdog timer, three-channel multi-function 16-bit pulse-width modulation (PWM) timer and an analog comparator that supports high-precision analog-to-digital conversion for cost sensitive applications.
There are also four analog comparators, each with their own dedicated 12-bit reference Digital-to-Analog Converter (DAC); and two programmable gain amplifiers to reduce external component count.
As a microcontroller board with a "bigger spark," the Uniti ARC is powered by an ATmega64M1 at 16 MHz, comes with a 12-bit high speed three phase motor controller, CAN 2.0 A/B transceiver for real-time communication, 10-bit digital to analog converter and four analog comparators. In addition, it can easily be programmed using the Arduino IDE.
Analog comparators are another type of peripheral devices which have found their way inside the microcontroller.
Three on-chip analog comparators further reduce system cost and the number of external components required.
