TS374CD

A linear comparator is a type of device used to compare two input signals and then detect a difference or a change in one of the signals. The linear comparator TS374CD is mainly used to monitor the dynamic change of analog signals, it can compare the voltage of two channels for electronics measurements and provides digital output for further processing. It’s designed for circuits with a 0-5V common-mode range and 5V to 10V input differential range. With the advanced operation principles and technology, more and more applications can benefit from the great performance of this device.

Features and Specifications

The TS374CD is a linear comparator that can compare two analog signals with a high degree of accuracy. It features a 0-5V common-mode range and 5V to 10V input differential range. The device also has a bandwidth of up to 150 MHz. The operating temperature range of the TS374CD is from -55 to +125 degrees Celsius. The device can detect a small change in the input signal of 1mV and provides a reliable digital output. It has a low power consumption (1mW typical) and is RoHS-compliant. The package of the TS374CD is a 8-lead SOIC package.

Working Principle

TS374CD linear comparator is designed to compare two input signals and detect changes in one of the signals. The device works by detecting the differential voltage between the two inputs and then providing a digital output. The input is compared to the reference voltage set by a resistive divider network. A transistor buffer is connected at the output, which is used to amplify the output signal and make it compatible with digital circuits.

When the input signals are equal, or within a certain range of each other, the output will remain in a low state, with certain hysteresis. When the difference between the two inputs exceeds the hysteresis range, the output will go high. The value of the hysteresis can be adjusted by adjusting the values of the resistors in the divider network.

The TS374CD linear comparator is used in a variety of applications, including:

• Power supply monitoring
• Linear data acquisition
• Analog-to-Digital (A/D) converter
• Difference amplifier
• Oscilloscope trigger
• Data and signal logging
