Opamp used as a comparator

Web26 de jul. de 2024 · Compared to DC voltage/very low frequency based comparator applications, the High-Frequency Comparator applications require additional parameters and considerations to provide better signal processing efficiency. Like DC Voltage applications, in High-Frequency applications also, the Op-Amps are being used instead … Web1 de nov. de 2024 · A comparator generates an output signal that indicates which of two input signals has the higher voltage. An op-amp can function as a comparator because it combines a differential input stage with very high gain. A voltage-reference IC or a resistive divider can be used to generate a threshold voltage for comparator circuits.

Web13 de set. de 2024 · If this sounds odd, then you can consider two fundamental (and seemingly equivalent) components: comparators and operational amplifiers. Note that an operational amplifier can be used as a comparator, but not all comparators act like amplifiers, thus the two terms are sometimes used interchangeably. WebIt’s not a 741 either! Lol. Blasphemy! This is likely for mains, BT137 is a triac, other components suggest common circuitry for a phase control mains dimmer. Most common was U2008B in the old days, this one does not look like that. Seems like a lot of people (including my first thought) said 555 timer.
