Linear-Comparators are used in a variety of applications, from motor control to remote sensing to ultrasound imaging. The MAX901AESE+ is a general-purpose comparator based on the Linear-Comparator family, and is suitable for a range of different industrial and automotive applications. This article will discuss the MAX901AESE+\'s application field and working principle.
Application Field
The MAX901AESE+ is designed to compare two input signals and to produce an output state that is dependent on the value and direction of the comparison. This makes the MAX901AESE+ ideal for use in many applications, including motor control, remote sensing, and ultrasound imaging. The MAX901AESE+ is also a suitable choice for ambient-light sensing and optical comparator applications, where a light signal is compared to a reference. With a wide supply voltage range of 3V to 16V, the device can also be used in low-power, low-voltage applications.
The MAX901AESE+ features an open-drain output, eliminating the need for voltage translation or pull-up resistors, and features a wide operating temperature range of -40°C to 85°C, making it suitable for harsh-environment applications. Additionally, the MAX901AESE+ features low-power operation and low-input offset voltage for superior accuracy when comparing signals.
Working Principle
The MAX901AESE+ is essentially a differential amplifier with its output state being determined by the differential voltage of its two inputs, Vin- and Vin+. When the voltage of the Vin- input is higher than the voltage of the Vin+ input, a high signal (VOUT) is generated, while when the voltage of the Vin+ input is higher than the voltage of the Vin- input, a low signal (VOUT) is generated. When the two input voltages are equal, the output is held in its last state.
The MAX901AESE+ has a low-voltage reference on the VREF pin, which can be used as a reference voltage for the Vin- input, instead of using an external variable reference voltage. The reference voltage, VREF can be adjusted using an external resistor to provide precise control of the switch point between the high and low output states of the MAX901AESE+. Additionally, the VREF pin can be used to adjust the hysteresis. By default, the hysteresis of the MAX901AESE+ is approximately 0.45V, with a hysteresis range of 0.2V to 1.5V.
Conclusion
In conclusion, the MAX901AESE+ is a general-purpose Linear-Comparator that is suitable for a variety of industrial and automotive applications. Its open-drain output eliminates the need for voltage translation or pull-up resistors, and its wide operating temperature range, low-power operation and low-input offset voltage make it ideal for applications that require accuracy and precision. Additionally, the MAX901AESE+ features adjustable hysteresis and a low-voltage reference on its VREF pin for precise control of the switch point and hysteresis.
