MAX998ESA+T is a monolithic CMOS low-power, low-cost comparator with built-in hysterisis, an open-collector output, and a logic-controlled output. It is capable of replacing general purpose TTL bipolar op-amps and comparators for most applications. This device belongs to a family of linear-comparators that are used in a broad range of analog circuits and systems.

A linear-comparator is a type of analog circuit used for comparing two analog input signals. It is used to detect the presence of a signal or to compare two inputs for equality. Linear-comparators, also known as voltage-comparators, allow for the quick and easy comparison between two input signals, meaning they can quickly tell you which signal is greater than the other. Comparators have the ability to quickly and accurately detect the presence of a signal or detect differences between two signals.

The MAX998ESA+T utilizes advanced CMOS process technology and comes in a small 8-lead, SO-10 package. This comparator is specifically designed to provide excellent differentiation of analog inputs. It has a wide operating range of supply voltage and temperature, making it ideal for most general-purpose applications. The comparator also has an impressive offset voltage, which is one of its most distinguishing features. This feature ensures that the comparator operates completely independent from any load or external noise.

The MAX998ESA+T operates by outputting a logic state (high or low) based on whether one of the two inputs is greater than the other. A user is able to define which polarity of the two inputs will result in a logic high output, which can be expressed in the following equation:

Output = VinP > VinN ? Logic High : Logic Low

VinP and VinN represent the two input voltages with VinP being greater than VinN. The comparator is built with an open-collector output, meaning that the output of the comparator can be connected to other logic elements or systems and will actively drive the logic high or logic low state as defined by the equation above. It is important to note, however, that a pull-up resistor must be connected to the output if the logic system does not have an internal pull-up resistor.

The MAX998ESA+T is suitable for use in a variety of applications, such as temperature monitoring, motor speed control, motor direction control, motor driver circuits, and power supply sequencing. It is also frequently used in medical, automotive, and industrial applications. Its specifications make it a suitable choice for applications that require precision, low power consumption, and flexibility.

The MAX998ESA+T is a valuable tool in many analog circuitry systems due to its low-power consumption and the fact that it operates independently from the load. The built-in hysterisis provides excellent differential between two inputs, making it a great option for any application that needs to accurately differentiate between two signals. All these features make the MAX998ESA+T ideal for use in a variety of applications and systems.
