You think of op amps as amplifiers because, no kidding, it is right in the name. But just like some people say, “you could do that with a 555,” [Doctor Volt] might say, “you can d… ...

A simple robot you can assemble for under $10 based on an LM358 Op Amp Comparator IC, Photoresistors, and other common components it uses for its line detection and following abilities. Dive into ...

Figure 4: Basic use of an op amp as a comparator (left) and an improved circuit with hysteresis to reduce sensitivity to noise (right). (Image: Renesas) Summary Op amps and comparators are similar but ...

This paper describes a high temperature voltage comparator and an operational amplifier (op-amp) in a 1.2-μm silicon carbide (SiC) CMOS process. These circuits are used as building blocks for ...

Basic Op-Amp Circuits Comparator circuit A comparator circuit (Fig. 1) compares two input voltages and outputs a binary signal indicating which is larger.

In this circuit, the output load voltage requirement is less than the comparator or Op-Amp output voltage level. In case the LED and Buzzer need to be connected in series, then the circuit has to be ...
