MAX923ESA-T

Linear comparators are electronic components used to compare two input signals and indicate, through logic output, when one signal is greater than the other. The MAX923ESA-T is a dual single-supply comparator which operates from a single 2.7V supply to a maximum supply voltage of 16V.

This component is designed to work equally well with both TTL or CMOS logic levels, providing two individually controllable outputs. It has an impressive response as it can be activated with as little as 0.3mV N.C. voltage differential between input voltages.

The MAX923ESA-T has an open drain output, which means that it is responsible for sinking current rather than sourcing it. This facilitates its use with power supplies of different types and voltages. The current it can sink is highly dependent on the amount of capacitance at the gate of the output transistor.

As far as applications are concerned, the open drain characteristic of the MAX923ESA-T allows it to be used in a wide range of applications. It can be used to detect over-current in consumer electronic devices and even provide a shutdown function for power supplies. It can also be used for monitoring and detecting open and short circuit faults in various circuits. Its wide supply range means it can be even used in low voltage circuit designs.

The MAX923ESA-T can also operate as an analog to digital converter, with two separate inputs allowing a user to measure two independent analog signals. Its CMOS logic output and low voltage supply range make it suitable for use in high density digital designs.

In terms of its working principle, the MAX923ESA-T contains a pair of two individual operational amplifiers. This allows two input signals to be compared to determine which is greater. The output circuit has an open collector, which is activated when one input is greater than the other, thus providing a logic output.

Overall, the MAX923ESA-T is an incredibly versatile component with a wide range of potential uses. Its low voltage supply operations, open collector output structure, and dual input capability make it a great choice for many different applications.
