The MAX903ESA+ is a dual high-speed CMOS comparator with microprocessor-ready outputs that have extremely low propagation delays of 8.5 and 6.5ns respectively. It is part of a series of low-power, high-speed, single- and dual-output comparators with rail-to-rail inputs from Maxim Integrated. This series is designed for cost-sensitive applications, providing precision accuracy and ultra-low power consumption. The MAX903ESA+ can operate with rails as low as 2.7V, ideal for powering with a coin-cell battery, and the entire series is immune to latchup.

The MAX903ESA+ belongs to the Linear-Comparators category. A linear, or linear-input, comparator is an electronic device that compares two input voltages, either sorting them as either higher or lower than each other, or determining whether one is equal to, lower than, or higher than, the other. The input voltages are fed into an amplifier circuit where they are compared with one another, resulting in either a high or low output voltage. This type of comparator is commonly used in logic circuits and feedback loops, as well as in A/D (analog-to-digital) conversion schemes.

The MAX903ESA+ features low power consumption of just 2.5mA, with a typical output delay of 8.5ns and 6.5ns respectively. The device utilizes a wide operating voltage range of 2.7V-5.5V, and can be used for the most current designs for minimum power consumption and fast performance. The MAX903ESA+ has excellent dynamic performance at 25MHz, and an open-drain output with symmetrical rise and fall times of 40ns in a 16-pin TSSOP package. Additionally, the device offers lower power dissipation than other comparators thanks to its low offset voltage and low input current.

In addition to its low level of power consumption and dynamic performance, the MAX903ESA+ has several characteristics that makes it an ideal candidate for a wide range of applications. These include low voltage operations, high common-mode rejection, low jitter, and the ability to span a wide range of supply voltages. The device\'s symmetric output rise and fall times make it ideal for powering microprocessors. It is widely used in many analog control and monitoring applications, such as over-voltage and under-voltage detection, temperature monitoring, touch screen controllers, and medical signal processing.

The MAX903ESA+ provides a number of advantages for use in linear-comparator applications. Its low power consumption allows for optimal battery life, and its wide voltage range allows it to be used in a variety of applications. Its low-offset capability ensures that any difference in input voltage levels is accurately measured, and its symmetrical output rise and fall times are ideal for powering microprocessors. Additionally, the device features high common-mode rejection and low jitter, making it a great choice for applications that require precise measurements. With these features, the MAX903ESA+ is the ideal device for use in applications requiring linear-comparator circuits.
