The MAX903CPA+ is a dual high-precision comparator belonging to the Linear - Comparators category. It is designed for precision applications such as data converters, temperature sensors, and thermocouples. It features a low input bias current of only 1 pA and ultra-low operating power of 50 μA per comparator. It also features hysteresis and common mode rejection of 2 V/V for better noise immunity and stability over an extended temperature range. The MAX903CPA+ is also available in an all-plastic 8-pin package.

The working principle of the MAX903CPA+ is based on an amplifier configured in a comparator topology. The input signal is applied to the non-inverting (positive) input and connected to the output node through a differential amplifier which is the core of the comparator. When the voltage at the non-inverting input is above the reference voltage, the comparator output goes high. On the other hand, when the voltage at the inverting (negative) input is higher, the output goes low. The differential amplifier amplifies the difference between the inputs and provides the desired voltage level at the output.

The MAX903CPA+ has many applications in various fields. In the data conversion and signal conditioning field, it can be used for filtering, level shifting, sample and hold, and multiplexing operations. It can also be used for temperature sensing applications such as gas sensing, resistance temperature detectors, and thermocouples. In automotive applications, the MAX903CPA+ can be used for voltage and current sensing, as well as for low-power power management.

The MAX903CPA+ is a highly integrated device and can be used in many different applications. It offers low input bias current, high accuracy, and low power consumption. The device also features hysteresis and common-mode rejection for improved stability over a wide temperature range. With its extended temperature range, it is ideal for applications in harsh environments and industrial applications such as safety and data transmission.
