Features: TLV3501 is a high-speed comparator that can be used to shape input signal waveforms and output TTL level signals. Features fast propagation delay of 4.5ns, supply voltage: +2.7V to +5V, and overswing input common mode range, for ideal for low voltage applications. Can be used in high-speed dagger comparator circuits, and the rail-to-rail output can directly drive CMOS or TTL logic. The module can shape periodic signals over a wide voltage range and serve as a front-end conditioning module for time-domain measurements such as frequency and phase difference. Applications: 1. Sine wave to square wave 2. Zero-crossing comparator 3. General purpose comparator.
