Working Principles

The EL8401IU is a voltage feedback operational amplifier that amplifies and conditions electrical signals. It operates by taking the difference between the non-inverting input (IN+) and the inverting input (IN-) and amplifying this difference with high gain. The amplified signal is then available at the output pin (OUT). The amplifier operates on a single supply voltage, making it suitable for a wide range of applications.

Detailed Application Field Plans

The EL8401IU is commonly used in the following application fields:

1. Audio Amplification: The high gain and low noise characteristics make it ideal for audio signal amplification in audio systems, such as amplifiers and mixers.
2. Sensor Signal Conditioning: The amplifier can be used to condition weak sensor signals, improving their accuracy and reliability in applications like temperature sensing and pressure measurement.
3. Communication Systems: The wide bandwidth allows for amplification of various communication signals, making it suitable for use in wireless communication systems, modems, and transceivers.

Detailed and Complete Alternative Models

1. EL8402IU: Similar to EL8401IU but with dual operational amplifiers in a single package.
