An electronic circuit that makes a comparison between two voltage levels or input signals is called a comparator. This IC compares the two applied inputs to it & generates an output that specifies which of the inputs is lesser or greater. If the non-inverting input is higher as compared to the inverting input, then output goes high and if the inverting input is higher as compared to the non-inverting, then output goes low. There are different types of comparator ICs like LM311, LM393, LM2903 … [Read more...]
What is a Comparator – Types & Its Working
Comparators are classified into various kinds, such as electronic, electrical, mechanical, optical, sigma, digital and pneumatic comparators, these are used in various applications. Comparators play an essential role in designing electrical and electronic projects. In electronic circuits, an op-amp is used with negative feedback and it can also be used as a comparator. The comparator is mainly designed without feedback for open loop configuration. These are widely used in A/D converters. When … [Read more...]
LM324 Comparator Circuits Working and Applications
The LM324 operational amplifier IC can be worked as a comparator. This IC has 4 independent operational amplifiers on a single chip. This a Low Power Quad Operational Amplifier and it has high stability, bandwidth which was designed to operate from a single power supply over a wide range of voltages. The quad amplifier can operate at supply voltages as low as 3.0 V or as high as 3.2 V with quiescent currents about one fifth of those associated with the MC174. … [Read more...]
