Comparator parameters

Comparator classification by major parameters

●

Propagation delay

●

Current consumption

●

Output stage type (open collector/drain or push-pull)

●

Input offset voltage, hysteresis

●

Output current capability

●

Rise and fall time

●

Input common mode voltage range.

Besides major parameters, comparators are classified by other parameters such as input

bias current, common mode and power supply rejection ratio, sample/hold function, and

startup time.
