What is the formula for the output voltage (Vout) of a comparator operational amplifier (AOP)?
The comparator AOP does not have feedback, which is known as open loop due to the operational gain set by the manufacturer, that is, we cannot control the gain.
The gain (A) is a constant of 105.
We frequently need to compare one voltage with another to verify which one is higher.
Vout = A . ( V+ - V- )
Vout = A . ( V- - V+ )
Vout = ( V+ - V- ) / A
Vout = ( V- - V+ ) / A

A fórmula correta para a tensão de saída (Vout) de um amplificador operacional comparador (AOP) é Vout = A . ( V+ - V- ), onde A é a ganho do amplificador operacional e V+ e V- são as tensões de entrada positiva e negativa, respectivamente. Como o AOP comparador não possui realimentação, ele é considerado um circuito de malha aberta.
