The LF247DT is a general purpose dual matched bipolar silicon integrated circuit that is specifically designed for transducer applications. The LF247DT can be used in applications including loop detectors, ultrasonic level detectors, contactless liquid level detectors, acoustic detectors, and many other types of position sensing devices. It is also used in seismometers, tilt meters, and industrial process control systems, as well as in robotics and automation applications. The LF247DT provides excellent sensitivity and stable performance over a wide band of frequencies and temperatures.

The LF247DT is a specialized device that converts a mechanical force, such as from a moving fluid or an oscillating coil, into a proportional linear output. It contains two matched electrical outputs, each having a respective independent input. The outputs can be used to provide a proportional linear output for a transducer, for driving an amplifier, or for sending a signal to a data acquisition system. The outputs are matched to each other to provide the same output voltage regardless of the input. The LF247DT is designed for accuracy over temperature and humidity ranges, so it is ideal for use in temperature and humidity monitoring systems.

The LF247DT achieves its accuracy through a combination of several design elements. The transducer or electrical input is converted to an output signal by a pair of high-gain operational amplifier modules. The modules amplify the input signal to a level sufficient to drive a linear voltage divider to generate the output voltage. The outputs are buffered and regulated to ensure exact repetition of the response at each input. Finally, the outputs are temperature compensated to maintain stability in changing temperature and humidity environments. The combination of all these design improvements provides stability and repeatability in the output.

The LF247DT has several useful features including on-board self-calibration circuitry and adjustable gain. The on-board self-calibration circuitry ensures accurate linear output for any given input. The adjustable gain allows the user to tailor the output response to the desired application. Additionally, various input and output configurations are available, allowing the user to customize the transducer setup to the needs of their specific application.

The LF247DT is an ideal solution for transducer applications that require an accurate, repeatable response over a wide range of temperatures and humidity ranges. It offers excellent sensitivity and linearity, and its adjustable gain, self-calibration circuitry and various input and output configuration make this a highly versatile and useful device for many types of applications.
