LM111 is a voltage comparator IC that has input currents nearly a thousand times lower than devices like the LM106 or LM710. The IC has a range of working conditions a wide range of working voltages and possesses direct interfacing capability with almost every PMOS, CMOS, and NMOS device. Moreover, the IC offers a wide array of features such as high noise immunity, ESD barring/reduction, and exceptionally low power dissipation.
Voltage Comparator
A voltage comparator can be defined as an electronic circuit that can compare two input voltages and distinguish which one of them is at a higher level of amplitude.
There are two main types of voltage comparators:
- Non inverting Comparators
- Inverting Comparators
Non – Inverting Comparators
A non-inverting comparator is an op-amp based comparator for which a reference voltage is applied to its inverting terminal and the input voltage is applied to its non-inverting terminal.
Inverting Comparators
An inverting comparator is an op-amp based comparator for which a reference voltage is applied to its non-inverting terminal and the input voltage is applied to its inverting terminal.
