This article discusses the application field and working principle of the FDA801B-VYT, a linear amplifier commonly used in audio applications.The FDA801B-VYT is a linear amplifier commonly used in audio applications. It is a dual-channel amplifier that is capable of handling both left and right audio signals simultaneously. The maximum output power of this amplifier is 120 watts per channel, allowing it to easily drive even the most demanding of audio systems.The FDA801B-VYT has a low distortion ratio of 0.005%, making it ideal for applications that require pristine audio signal quality. It also has an unusually high signal-to-noise ratio of 120dB, ensuring that the audio signal is free from noise and distortion. Additionally, the FDA801B-VYT has low harmonic distortion of 0.006% (THD+N).The FDA801B-VYT has a wide range of other features that make it suitable for audio applications. These include a high input impedance of 10K ohms, a low output impedance of just 0.6 ohms, a maximum input level of +30dBu, and a wide frequency response of 20Hz to 20kHz (+/- 1dB). Additionally, the FDA801B-VYT has a low charge pump voltage of 3.3V.The working principle of the FDA801B-VYT is fairly simple. The amplifier takes the incoming signal and amplifies it before sending it out in a much higher voltage. This is done using an input stage, a differential amplifier, and a voltage amplifier stage. The input stage amplifies the incoming signal, which is then sent to the differential amplifier, where it is further amplified. Finally, the amplified signal is sent to the voltage amplifier stage, which boosts the voltage of the signal to a much higher level. This amplified signal is then sent out to the output, ready for use.The FDA801B-VYT is a powerful linear amplifier that is versatile enough to be used in a wide range of audio applications. It has a low distortion ratio, a high signal-to-noise ratio, and a wide frequency response. Additionally, it has a low charge pump voltage and a high input impedance, making it suitable even in demanding audio systems. The working principle of the FDA801B-VYT is fairly straightforward and easy to understand, making it a great option for those looking to get the best possible sound out of their audio systems.
