LX1721CDB Application Field and Working Principle

Linear amplifiers are used to amplify an input signal, usually to a higher voltage level. Audio amplifiers are amplifiers designed specifically for audio applications. They are designed to closely match the characteristics of the devices they are driving, and create minimal distortion.The LX1721CDB is a linear amplifier developed for use in audio applications. It has a maximum output of 210W RMS and a peak-to-peak voltage of 250V. It has a wide range of operation and can be operated from 1.5V to 20V. It is also flexible in terms of frequency range, with a broad frequency response going from 20kHz to 20MHz, making it suitable for many different audio applications. The LX1721CDB is a current gain amplifier, meaning it amplifies the current of a signal rather than the voltage. It achieves this by using a PNP and an NPN transistor connected in a common emitter configuration. This arrangement allows the amplifier to achieve higher gain by outputting a voltage that is larger than the input voltage.The LX1721CDB is ideal for driving speakers, players and other low impedance devices, thanks to its constant voltage gain,low harmonic distortion and low noise level. It allows for a high-quality audio reproduction with minimal distortion, making it well suited for use in professional audio applications.The LX1721CDB has a robust construction, with its components being well-suited to exposure to high temperatures, ensuring long-term reliability. The device also provides excellent thermal performance, as its well-designed heatsink ensures that it remains cool even during extended use.In conclusion, the LX1721CDB is a reliable, efficient and high-quality audio amplifier that is well suited for a range of audio applications. Its current gain transistor configuration ensures it can provide high-quality audio reproduction, whilst its robust construction ensures reliable operation even under extreme conditions.
