Miniature Class D Amplifier on a PAM8403 Chip by American Power Analog Microelectronics
The amplifier has a small heat dissipation, small size and affordable cost. Low distortion coefficient allows you to get high quality sound with sufficient output power. If there is noise when connecting, you must connect the volume control. The maximum output power of the amplifier is up to 3 W with a load of 4 Ohms.
The advantages of this amplifier:
- small sizes;
- low consumption at rest;
- high efficiency;
- the ability to work with low voltage power supplies;
- ease of connection and installation in any design;
- small dimensions and weight of the entire board assembly.
Supply voltage 2,5-5V.
This PAM8403 amplifier can be recommended for:
- amateur radio designs with high output sound signal power (including self-powered);
- a laboratory amplifier for tuning and repairing sound reproducing equipment;
- alterations of passive speakers into active ones.
