Linear-comparators are used to compare one signal with another, or one signal with a fixed reference level. The SC239DR2G is an example of such a comparator. It is a dual comparator with integrated circuits, making it a low power, small footprint solution for a wide range of applications.

The SC239DR2G is a low voltage dual comparator. It is designed to work with a single power supply of 2.7 to 5.5 V and has a low power consumption, ideal for applications where power conservation is important. The device is rated for an input voltage of up to 18 V and is protected against overloads up to 30 V.

The comparator consists of two independent op-amps and operates on the principle of comparing one signal with another, or one signal with a fixed reference level. The external components are used to set the desired hysteresis and can be used to create level shifting, phase shifting and frequency response control. The buffers can be used to form a differential amplifier or an adder circuit to construct an amplifier with high input impedance.

The SC239DR2G is pin-compatible with the LM339N and can be used in a wide range of applications such as digital systems, data converters, voltage regulators, analog-to-digital converters, IR receivers, filters, switched capacitor filters and other similar circuits. It is particularly useful in automotive systems as it has a low power consumption and a wide operating temperature range of -40 °C to +125 °C.

The SC239DR2G works by comparing one signal with another, or one signal with a fixed reference level. The reference level is set by the external components while the input signal is connected to the non-inverting input of the comparator. When the non-inverting input is at a higher voltage than the reference level, the output is high, and when the non-inverting input is at a lower voltage than the reference level, the output is low. This process is repeated for the other input, producing two outputs.

The SC239DR2G is a versatile, low-power comparator that can be used in a variety of applications from automotive systems to data converters. It operates on the principle of comparing one signal with another, or one signal with a fixed reference level and is rated for an input voltage of up to 18 V and is protected against overloads up to 30V. It is pin-compatible with the LM339N, making it an ideal solution for a wide range of applications.
