Comparators have an op-amp front end and a digital back end that operates like a gate. The comparator output stage may be an open collector transistor, so it often connects to the logic supply through ...

[Dan Kouba’s] parents replaced their doorbell button with one that lights up and found that the chime wouldn’t stop sounding after the button was pushed. These lighted buttons use an incandescent bulb ...

A common feature in most of the electronic devices we use – cell phones, PDAs, notebooks, handheld media players, game systems, etc. – is the provision for connecting external accessories. Such ...

Toshiba releases a CMOS dual comparator with a high-speed response and a full I/O range for use in overcurrent detection in ...

In this paper, the authors introduced a 4 bit flash analog to digital converter. The propose ADC consist of the comparators and the MUX based decoder. Propose comparator eliminate the use of resistor ...

A custom comparator IC that has fast response time and hysteresis protects a car's engine control unit from failures on monitored peripherals that create high current conditions. In most modern cars, ...

With modern microcontrollers, the process of interfacing with the analogue world is easy. Simply enable the on-board DAC or ADC, and talk to the world. If you’ve ever done this with a slightly older ...

If you're seeking a way to measure current and power in a circuit, you need to know about current-sense amplifiers (CSAs). A CSA is a specialized op amp connected as differential amplifier with ...
