Audio amplifier integrated circuits are equipment embedded in electronic circuits for audio applications. They are being used to enhance the properties of the embedded audio system. To name a few, audio amplifiers increase, the control and amplitude of the signals. Audio signal enhancement has been possible by using just this equipment in terms of sound and quality. The amplifier is characterized by its excellent performance and classification, which makes use of letter symbols such as:
- Class-A
- Class-B
- Class-C
- Class-D
- Class-AB
The integrated circuit audio amplifiers are the modified versions. This modification makes them popular because of the huge size transformation into a small size. Not it is possible to manufacture an innovative amplification within a small embedded system. Unlike power amplifiers, which are combinations of many components, Audio amplifiers are widely available and manufactured from standard semiconductor packages, and it is also possible to through-hole and surface mount them, such as:
- HTSSOP
- MSOP
- PDIP
- SOIC
- TQFN
What are the types of Audio Amplifiers?
- Microphone Pre-Amplifier
- Headphone Amplifier
- Audio Amplifier
- Audio System
- Bridge Amplifier
- Compandor
- Speaker Amplifier
- Operational Amplifier
- An audio power amplifier
- Audio Line Drivers
Specifications you must know when choosing an Audio Amplifier:
- Maximum Power - Given in watts, based on the size and utilization of amplification you need.
-
Input Signal type - This is embedded in standalone-ended and/or differential inputs.
-
Output Type - Mono outputs have one medium, while stereo outputs have more than one.
-
Output signal type - This is typically integrated within applications that have single-ended and/or differential outputs.
What are the applications of Audio Amplifier ICs?
Audio amplifier ICs are widely employed in a range of household and commercial applications. They are typically embedded in televisions, keyboards, car stereos, headphones, televisions, and toys. Moreover, they are also being employed in electronic circuits such as line drivers, radio amplifiers, ultrasonic drivers, and power converters.
