Introduction

The MAX9108EUD+ is a single-supply micropower comparator with a low supply current that is ideal for portable and battery-powered applications. The MAX9108EUD+ is also available in an auto-shutdown mode to reduce the power consumption during idle periods. This comparator is suitable for use in applications such as low-power temperature measurement and single-supply level shifters.

Description

Comparators are linear circuits in which an output voltage is generated that is proportional to the difference between two input voltages. The MAX9108EUD+ utilizes an input stage that is externally matched to provide a rail-to-rail input range. Transistors are used to ensure the inputs remain linear over the entire range. In order to optimize the data transfer rate, the delay time between input and output is minimized. The MAX9108EUD+ uses hysteresis per output to help filter out noise at the input stage.

Features

The MAX9108EUD+ provides several features that make it an ideal choice for low-power applications. The main features are low input bias current, low supply current, wide supply range (2.4V to 16V), auto-shutdown mode, rail-to-rail inputs, and a programmable comparator output. The low input bias current ensures the input will not drift as the device ages, while the low supply current ensures that power consumption is minimized. The wide supply range enables the MAX9108EUD+ to operate in a variety of operating environments. The auto-shutdown mode reduces power consumption to negligible amounts during periods of inactivity. The rail-to-rail inputs allow the device to take full advantage of the input voltage range. And the programmable comparator output provides some flexibility when selecting the desired output logic level.

Applications

The MAX9108EUD+ can be used in a variety of applications. Its low input bias current and low supply current make it an ideal choice for portable and battery-powered applications such as hearing aids, breathalyzers, or medical devices. It is also suitable for temperature measurement and single-supply level shifters. The rail-to-rail inputs enable the MAX9108EUD+ to take full advantage of the input voltage range. The programmable comparator output enables the specification of the desired output logic level.

Conclusion

The MAX9108EUD+ is a single-supply micropower comparator with a low supply current that is ideal for portable and battery-powered applications. Its features include low input bias current, low supply current, wide supply range, auto-shutdown mode, rail-to-rail inputs, and a programmable comparator output. The MAX9108EUD+ can be used in a variety of applications such as hearing aids, breathalyzers, medical devices, temperature measurement, and single-supply level shifters.
