Linear - Amplifiers - Audio

MP1720DH-12-LF is a popular audio amplifier applied in many fields. This device has many characteristics, such as low saturation current, dust-proof sealing and full frequency response characteristics below 20kHz, which makes it popular with many engineers. In addition, it also has excellent resistance to temperature and environmental changes, making it suitable for such a wide range of applications. Its basic principle of working can be outlined as follows.

Overall working principle

An audio amplifier is a circuit which amplify the sound signals for the purpose of boosting the audio signals and providing additional output power to the speaker. The input to an amplifier is an electrical signal which is usually a microphone or a musical instrument. This input signal increases the power of the sound waves, which are then output from the speaker. In order for a speaker to receive the boosted sound, the amplifier requires a power source, this power source can either be direct current (DC) or alternating current (AC).

Principle of MP1720DH-12-LF operation

The principle of operation of the MP1720DH-12-LF device is in the same category of audio amplifiers. First, the input signal is passed through a preamplifier which amplifies the signal to the level needed for the amplifier to work properly. Then the power amplifier boosts the signal according to the user’s specifications. The output of the power amplifier is usually a voltage which directly drives the speaker. The amplifier should also be able to deliver the required current to the speaker, for the ultimate sound quality.

Features and applications

The MP1720DH-12-LF has a low saturation current and full frequency response characteristics below 20kHz. Moreover, due to its dust proof shell, the device can be used in dusty places. This dust-proof sealing ensures that the quality of the sound does not degrade due to dust and foreign particles. Moreover, its excellent resistance to temperature and environmental changes make it suitable for a wide range of applications including audio systems, public address systems and car audio systems.

Summary

MP1720DH-12-LF audio amplifier is widely applied in many fields because of its excellent characteristics. It has low saturation current, dust-proof sealing and full frequency response characteristics, as well as excellent resistance to temperature and environmental changes.
