The LF347BD is a "Quad" device that contains four independent high-gain, internally-frequency compensated Operational Amplifiers. The LF347BD has a typical gain of 10 million and an open-loop voltage transfer of 1MHz. It is a low power quad op-amp with a high speed response time of 1nS and an extended temperature range from -65°C to 125°C. The LF347BD is designed for applications where high speed, low noise, and low power consumption is required.

The LF347BD is classified as a Linear, Amplifiers, Instrumentation, OP Amps, Buffer Amps type device. It has four independent precision amplifiers in a pentawatt package. It is designed to provide a full POWER frequency response due to its high gain, low power consumption, fast response time, low noise, and extended temperature range. The LF347BD has two wide supply voltage ranges of +/-2.0 to +/-18V and +/-3.0 to +/-32V, making it suitable for many different applications. Its common-mode input voltage range includes ground, and these amplifiers can operate from a single supplies Transistor-Transistor Logic (TTL) compatible inputs.

The LF347BD Functional Operating Principle includes the concept of negative feedback, wherein a signal is fed back from the output of an amplifier to its input. The signal is compared with the incoming signal from the input and any signal differences are corrected by the amplifier until both signals are identical. In this manner, the output signal is nearly identical to the input signal and any undesired signal distortion is greatly reduced. The feedback frequency of the amplifier is determined by the internal components of the LF347BD and the frequency response is determined by the amount of feedback.

The LF347BD is suited for a wide range of applications due to its low noise, low power Operation, fast response and extended temperature range. They are designed to provide amplification with minimal distortion and low power in instrumentation and medical applications. Other applications include power management, signal processing, precision control, audio applications, and RF/IF filters.

The LF347BD is a versatile and reliable device for applications needing precision output. It is capable of both low power and high performance with its small size and extended temperature range. It can offer the design engineer a wide range of capabilities, making it a sought after device for many projects.
