Specification:
Descriptions:
is a single-channel high-speed push-pull output comparator, delay is 4.5ns, supply voltage: + 2.7V to + 5.5V, has exceeded swing input common-mode range makes it ideally suited for low voltage applications. Rail-to-rail output can directly drive a CMOS or TTL logic. This module can be for a wide range of voltage signal shaping period, as the frequency, phase difference time domain measurements and other front-end conditioning module, can be used as the 2015 National Undergraduate Electronic Design Contest F digital frequency meter title front-end module.
Features:
is a single-channel high-speed push-pull output comparator, delay is 4.5ns, supply voltage: + 2.7V to + 5.5V.
This module can be for a wide range of voltage signal shaping period, as the frequency, phase difference time domain measurements and other front-end conditioning module.
Rail-to-rail output can directly drive a CMOS or TTL logic.
Without threshold setting, the sine wave, square wave and triangular wave can be transformed into square wave, which can be used easily without debugging.
At the same time, it has great extensibility, just change a small amount of the original.
