Linear - Comparators

The MAX902CSD-T is a linear comparator circuit which uses a dual op-amp and a 3.2V voltage reference. It is designed for use in circuits with external reference inputs and is powered by a single supply operating range of 4.5V to 18V. Its operating frequency is up to 100kHz, making it suitable for applications that require high response speed. Its tri-state output can be used as a single output, or as part of a two-stage comparator circuit.

Application Field

The MAX902CSD-T is ideal for many applications that require a comparator. It can be used to compare two signal levels and will output a logic high or low depending on the input signal levels. Common applications include an amplifier without dc offset, an AC signal monitor, an overcurrent protection circuit, an oscillator circuit proportion adjustment, and a pulse waveform width control circuit.

Working Principle

The circuit is designed such that it will compare a signal to a reference voltage generated by its integrated voltage reference input. If the signal exceeds the voltage reference, the output of the comparator will go high, otherwise it will stay low. Once the voltage reference is established, the output of the comparator will change instantly when the signal level reaches the reference. Thus, this circuit can act as a notification of when a certain signal level is reached.

Conclusion

In conclusion, the MAX902CSD-T is a linear comparator with a reference voltage input and a tri-state output. It is suitable for many high-speed applications due to its fast response time and can used in amplifier without dc offset, an AC signal monitor, an overcurrent protection circuit, an oscillator circuit proportion adjustment, and a pulse waveform width control circuit.
