General Description
Key Specifications
The HWD2108 is a dual audio power amplifier capable of n THD+N at 1kHz at 105mW continuous average output
delivering 105mW per channel of continuous average power
power into 16Ω
0.1% (typ)
into a 16Ω load with 0.1% (THD+N) from a 5V power supply. n THD+N at 1kHz at 70mW continuous average output
audio power amplifiers were designed specifically to provide high quality output power with a minimal amount of external components using surface mount packaging. Since
power into 32Ω
