Features: 1.TLV3501 is a single high-speed push-pull output comparator: delay is 4.5ns, supply voltage: + 2.7V to + 5.5V.2.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.3.Rail-to-rail output :can directly a CMOS or TTL logic.4.Without threshold setting: the sine wave, wave and triangular wave can be transformed into wave, which can be used easily without debugging.5.At the same time: it has great extensibility, just change a small amount of the original.Descriptions:1.Compact design, easy to install.2.Uses the high quality material: stable and reliable performance.Specifications:Supply voltage: 2.7-5VDCInput voltage: 8-1000mV (effective value)Output level: rail to rail output, can directly TTL / CMOS levelInput frequency: 1Hz-120 MHz, Min.1HzInterface shape: SMA female head (external screw hole)Input impedance: 20 K ohm Product Use:Sine waveThe zero crossing comparatorUniversal comparatorColour:greenMaterial:metal+pcSize:about 5 x 2.5cmPackage Contents:1 x High speed waveform comparatorOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
