The MAX944ESD+T is a precision comparator, featuring low offset and an inexpensive output transistor, making it an ideal choice for cost-sensitive applications. It operates from a single supply of up to 16 V and is capable of driving up to 24 mA load currents. It is housed in the industry standard 8-pin SOP package and is available in both the standard and extended temperature ranges.

A comparator is an electronic device which compares two input signal voltages, and changes its output state depending on which voltage is larger. The basic circuit consists of a voltage sensing stage and a comparison stage. The voltage sensing stage translates the incoming signal to a digital representation, while the comparison stage compares the two input signals and determines which voltage is larger. The MAX944ESD+T works in this fashion, except that it is a low-cost, precision comparator.

The MAX944ESD+T has a comparator input stage with a very low offset voltage. This ensures accurate and reliable comparison of input signals. The device also features a +2V/–2V output stage, which is used to drive the load currents up to 24 mA. The +2V/–2V output stage reduces power supply current, as it can operate at low levels when the load current is minimal, and can increase its output current when the load current requires it.

In addition, the MAX944ESD+T has an ‘open collector’ output which can be used to force the output of the comparator to a logical ‘high’ or ‘low’ state. When the output is forced to a logical ‘high’ state, all input signals above the threshold voltage will be accepted, creating a ‘window pulse’. When the output is forced to a logical ‘low’ state all input signals below the threshold voltage will be accepted, creating an ‘inverse window pulse’.

The MAX944ESD+T is suited for a wide range of linear applications, from level detection to pulse width modulation. The device is particularly well suited for automotive, industrial, and medical applications as it is able to operate from a single supply up to 16 volts, and is available in an extended temperature range. It also has a low cost compared to other precision comparators, making it an ideal choice for cost sensitive applications.

The MAX944ESD+T is an ideal accomplice for any high precision linear application, providing a low cost, high accuracy solution. Its features, such as the +2V/–2V output stage, open-collector output, and availability in the extended temperature range, makes this device suitable for many applications, ranging from automotive to medical.
