The AAT2810 is a Class-G audio power amplifier based upon a battery-tracking AGC technology. It can deliver up to 2.4W into an 8Ω load with 10% THD+N. Its high efficiency, up to 74%, helps greatly extend battery life for portable applications.
The AAT2810 employed by an internal charge pump generates a 6V supply voltage for the output stage of the Class-G audio amplifier, thus allowing a much higher output power than a conventional stand-alone amplifier directly connected to the battery supply voltage. The AGC technology allows the audio signal to be adaptively amplified for a maximum dynamic range of the output signal without clipping, which might be otherwise resulted from an over-level input signal or a lower supply voltage.
The AAT2810 incorporates a low-pass filter (100kHz) at the inputs to enhance RF rejection and reduce DAC out-of-band noise, therefore greatly improving the signal-to-noise ratio (SNR).
