The MAX931ESA+T with Maxim Integrated Analog Comparators Comparator w2% Reference is a precision, low-power, single-supply, 8-pin integrated circuit manufactured by Analog Devices. It is a simple, space-saving device designed for operation across a wide range of supply voltages and temperatures. This comparator has two built-in hysteresis amplifiers and is able to precisely compare two analog voltages, providing a wide range of signal gains for linear/logic control. It also has an adjustable “VOC” or voltage compensation circuit for precise voltage references, and provides an open-drain output configuration. Additionally, it has a wide bandwidth of up to 500kHz, allowing it to respond quickly to rapidly changing input signals. The MAX931ESA+T is perfect for applications such as AC and DC motor control, active filters, level detection, overload protection, and temperature sensing. Its low power consumption and high levels of accuracy make it a great choice for many automated systems.
