WebbAn op amp is a voltage amplifying device. With the help of some external components, an op amp, which is an active circuit element, can perform mathematical operations such as addition, subtraction, multiplication, division, differentiation and integration. WebbThe op-amp operates from 5V/0V so the output for a balanced bridge would be 0V, and it would not be able to go quite to 0V. Also, for a differential amplifier you'd normally want to connect the Vout+ to two resistors with ratio R2/R1 to …

Designing Switching Voltage Regulators With the TL494 (Rev. E)

A comparator consists of a high gain differential amplifier whose output is compatible with the logic gates used in the digital circuit. The gain is high enough that a very small difference between the input voltages will saturate the output, the output voltage will be in either the low logic voltage band or the high logic voltage band of the gate input. Analogue op amps have been used as comparators, however a dedicated comparator chip will generally be faster than a general-purpo… We have seen here that operational amplifiers can be configured to operate as comparators in their open-loop mode, and this is fine if the input signal varies rapidly or is not too noisy.
