The LF347DR is a small, monolithic and versatile integrated circuit designed for signal conditioning. It consists of a single low power op amp with two //JFET-inputs, independent electrical and thermal protection, and is specified to operate over a wide range of temperatures. The device has very low power dissipation, low noise and high common-mode rejection ratio, making it ideal for signal conditioning in instrumentation, medical, and photonic applications.

The LF347DR is used for simple signal conditioning applications, such as filtering, amplifying, level shifting, and providing adjustable gain. It is also used for applications such as analog-to-digital converters, amplifier sliders and mixers, level detectors, and signal conditioners. The device is also used in automotive and industrial control systems, providing signal conditioning for switches, sensors and logic circuits.

The working principle of the LF347DR is based on the integrated circuit\'s two //JFET-inputs. These two JFET\'s are connected in a push-pull configuration - one input to the positive supply voltage, the other to ground. The two JFET-inputs allow the device to operate over a wide range of input voltages and to operate with minimal power consumption. The device\'s common-mode rejection ratio makes it an excellent choice for signal conditioning in instrumentation, medical, and photonic applications.

The LF347DR also offers good differential common-mode rejection, with better than -110 dB at 1 kHz for a single amplifier configuration, and better than -120 dB for a dual amplifier configuration. The device is also capable of rejecting 60 Hz or higher noise from the input signal. The device has a very low power dissipation and low noise characteristics, making it an ideal solution for low power applications or anywhere a very low power is needed.

The LF347DR is a versatile, monolithic integrated circuit that is used for a wide variety of signal conditioning applications. It offers a wide range of features, including low power dissipation, low noise, and high common-mode rejection, making it ideal for instrumentation, medical, and photonic applications. With its easy to use configuration, it is a great way to improve signal conditioning and performance in a variety of applications.
