NCS2203SN2T1 Integrated Circuits (ICs)

Linear - Comparators

The NCS2203SN2T1 linear–comparator is an integrated circuit that can compare two voltage or current signals, or one current and one voltage signal and provide a digital indication or output when the mathematical relationship meets a predefined criterion. Comparators are widely used for many analog applications such as data conversion, signal conditioning, limit detection and time-based applications such as time base generation and pulsewidth detection.

Application Field

The NCS2203SN2T1 linear–comparator is used in applications which require high accuracy, low phase shift, high reliability and small size. Some of the common applications of the NCS2203SN2T1 linear–comparator are in process control, medical, automotive and industrial systems.

In process control, the comparator is used to detect limit values of inputs such as pressure, temperature, flow rate or level. It is used in medical systems to monitor patient vital signs such as heart rate, oxygen level and body temperature. It is also used in automotive applications to detect motion in seat systems, fuel level in gages and level of system performance.

In industrial systems, the comparator is used to detect the level of the line power in alternators, the speed of rotating operations and the purity of gases in leak detectors. Other applications include synchronizing distributed systems, voltage regulation and detection of a specific waveform.

Working Principle

The working principle of the NCS2203SN2T1 linear–comparator is based on difference detection. It has two inputs, one for the reference value and another for the input value (signal) to be tested against the reference. The output of the comparator is a digital signal, usually of low voltage, which indicates whether the input values satisfy the given criteria.

The comparator is designed to detect difference between the two signals and the level of the output signal is dependent on the level of difference between the two input signals. The output of the comparator can be in the form of an on/off signal or a pulse when the reference level is exceeded.

The comparator has a number of features including adjustable hysteresis, low offset voltage, low noise, low power consumption and excellent common mode rejection ratio. The output is generally TTL (transistor-transistor logic) compatible and is suitable for driving logic components.
