TLV3501 High Speed Comparator Frequency Meter Front Sha

Descriptions:

TLV3501 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.

  Without threshold setting, the sine wave, square wave and triangular
  
  wave can be transformed into square wave, which can be used easily
  
  without debugging.
