    • Application Field

      The LF247D is an op-amp integrated circuit that has been used in a variety of analog signal conditioning applications in measurement and test equipment, particularly instrumentation amplifiers. A wide variety of instrumentation amplifiers are available, including single supply, dual supply and micropower types designed for use in a variety of applications. The LF247D features a low-power, high-performance amplifier with excellent voltage and current noise ratio, frequency response and gain bandwidth. These features make the IC a great choice for signal conditioning applications that require reliable and accurate measurement of signals.

    • Working Principle

      The LF247D is a dual-channel, dual-supply voltage amplifier. The device can be operated from a single power supply between 5V and 15V with a maximum quiescent current of 390 µA. It features slew rate, gain bandwidth and voltage and current noise ratio specifications. The LF247D\'s circuit is designed to reject common-mode noises and to provide high CMRR. This amplifier consists of two independent stages, each with its own amplifier and output circuit. The two amplifiers are configured as an inverting amplifier, with a single output that sums the two stages\' signals and drives the output. The two stages can also be connected in a non-inverting configuration to create a differential amplifier. The LF247D\'s gain is adjustable over a wide range (1 dB to 10 dB) by changing the compensation network at the input stage of each amplifier. This allows flexibility and allows the designer to maximize the device\'s performance for a specific application.

      The LF247D is an ideal choice for designing instrumentation amplifiers. It has excellent noise characteristics, low power consumption, and the ability to be configured for a variety of applications. The IC\'s wide dynamic range and high CMRR make it well-suited for signal conditioning applications where noise is an issue. Additionally, the device\'s wide frequency response and adjustable gain make it an ideal choice for a variety of test and measurement applications.
