ft2811 2.4W Charge Pump Class-G Audio Amplifier GENERAL DESCRIPTION The ft2811 is a Class-G audio power amplifier with battery-tracking AGC technology. It integrates a charge pump and drives up to 2.4W into an 8 Ω speaker (10%THD). With 74% efficiency, the ft2811 helps extend battery life when playing audio. The built-in charge pump generates a 6V supply voltage for the Class-G amplifier. This provides a louder audio output than a stand-alone amplifier directly connected to the battery. The AGC technology helps to adjust Class-G gain automatically. The ft2811 has an integrated lowpass filter. It helps you get lower EMI noise and increase SNR.
