Description
PAM8302 Mono Digital Audio Amplifier Module is a tiny 2.5 Watts mono amplifier, which works at class D. The module can be supplied by a 2.0V-5.5VDC power source and produce a powerful amplified sound into a 4Ω or 8Ω impedance speaker. Due to working at class D, it has high efficiency (over 90% efficient when driving an 8Ω speaker at over half a Watt). Tiny size besides high efficiency make it applicable in widely portable and battery powered projects. Adjusting the output volume is done via a volume trim pot from zero to the default 24dB gain. The safety properties of the PAM8302 consist of protection against over-current conditions, and abnormal temperature conditions.uF capacitors, so they are fully '
