Linear - Comparators are a type of electronic circuit used for comparisons between two currents or voltages. The MAX9064EBS/TG45 is a high-performance, single-supply, low-power, bidirectional comparator with an adjustable hysteresis. The MAX9064EBS/TG45 features a wide operating supply-voltage range of 2.5 V to 16 V, and can be used in applications that require the detection of small differential signals in noisy environments.

The MAX9064EBS/TG45 comparator has an adjustable hysteresis that is externally controllable with a single resistor. This provides the ability to reject any noise present on the input signals and improve the comparator’s noise margin, while providing immunity to any power-supply-induced noise. The comparator also features an output signal that is always opposite in polarity to the input signal. This output polarity is useful in ensuring proper polarity when used in digital logic applications. In addition, the MAX9064EBS/TG45 reduces the need for external signal conditioning by providing a signal-acquisition time of 50 ns (typ).

The MAX9064EBS/TG45 is used in applications requiring fast detection of small differential input signals in noisy environments, such as in cell phones, video cameras, disk drive protection circuits, level detectors, and voltage detectors. The comparator is ideal for applications that require a low-power, full-featured comparator. The MAX9064EBS/TG45 is available in 8-pin MSOP and 8-pin SOIC packages.

The MAX9064EBS/TG45 works by using a pair of differential input amplifiers. The two input signals are amplified, and then compared to a reference voltage that is determined by an external resistor. If the input signals exceed the reference voltage, the output signal goes to its maximum value, indicating that the input signals have exceeded the reference voltage. This output signal can then be used to trigger some other action, or to generate an alarm signal. The output signal is opposite in polarity to the input signal, so the output can be used directly in many digital logic applications. The output signal also has an adjustable hysteresis threshold that can be adjusted to reject power supply-induced noise and to provide immunity to short-term noise spikes.

The MAX9064EBS/TG45 comparator is used in a variety of applications requiring the fast and accurate comparison of signals. It is particularly well suited for applications where one of the input signals is sensitive to noise, or for applications that require an adjustable hysteresis feature. The comparator’s low-power operation and ability to reject power supply-induced noise make it an ideal choice for battery-powered applications. In addition, its wide operating voltage range and fast response times make it suitable for a variety of applications in the communications, consumer, industrial, and automotive markets.
