The LF347BN is a high-performance monolithic, low-power, dual JFET op-amp with excellentDC stability and superior overloadrecovery characteristics. This type of op-amp is particularly well-suited for use in precision measurement and audio equipment, radios, and amplifiers. The LF347BN is also suitable for wideband and narrowband amplifiers, video amplitude modulators, and other applications that require high dynamic range and high common-mode rejection.

The LF347BN is a very versatile operational amplifier and its application field includes, but is not limited to, high-frequency amplifiers, instrumentation amplifiers, power supplies, oscillators, and other applications. It is a great choice for use in precision measurement and audio equipment, radios, and amplifiers. The LF347BN has a slew rate of 2V/μs and a bandwidth of 10 MHz, making it especially suitable for use in wideband and narrowband amplifiers and video amplitude modulators. It also has a high common-mode rejection ratio of 100dB, which makes it ideal for precision applications where minimizing of stray signals is crucial.

The working principle of the LF347BN is based on the concept of a differential amplifier. The amplifier consists of two input transistors, two current source transistors, two current source resistors, two bias resistors and one output transistor. The two input transistors are configured in a differential pair, with one input connected to the positive input and the other input connected to the negative input. The output of the amplifier is connected to the output transistor, which is responsible for providing the output voltage. The two current source transistors provide the bias current to the differential pair. The current source resistors and bias resistors are responsible for setting the bias of the differential pair and dynamically adjusting the gain.

The LF347BN is a great choice for many applications due to its low power consumption, high dynamic range, and high common-mode rejection. Its wide frequency range and fast slew rate make it ideal for a wide variety of applications. It can be used in audio amplifiers, instrumentation amplifiers, power supplies, oscillators, and other applications which require a combination of low power consumption, high dynamic range, and high common-mode rejection.
