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 formed 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: 2.7-5VDC Input voltage: 8-1000mV (effective value) Output level: rail to rail output, can directly TTL / CMOS level Input frequency: 1Hz-120 MHz, Min.1Hz Interface shape: SMA female head (external screw hole) Input impedance: 20 K ohm Product Use: Sine wave The zero crossing comparator Universal comparator Colour:green Material:metal+pc Size:about 5 x 2.5cm Package Contents: 1 x High speed waveform comparator Only the above package content, other products are not included. Note: Light shooting 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.
