AnalogicTech has developed the AAT5101, a 2,5 W Class D audio amplifier that combines low-voltage operation with low-quiescent current and standby current.
The mono power amplifier operates across a wide 2,1 V to 5,5 V supply voltage making it suitable for systems using next generation low-voltage Li-ion/polymer batteries. To further extend battery life, the audio amplifier delivers up to 92% efficiency and offers a very low 0,06 μA shutdown current and 1,35 mA quiescent current.
The AAT5101 outputs 1,35 W with an 8 Ω load and THD+N <1% and 2,5 W with a 4 Ω load and THD+N <10%. Its low noise, filterless PWM architecture simplifies system design by eliminating the output filter, reducing external component count. To ensure clean sound across the entire audio output range, the device delivers 0,12% THD+N at 5 V with 8 load and POUT = 1,0 W. PSRR is -60 dB, while SNR is 91 dB.
The new audio amplifier also features integrated thermal and short-circuit protection circuitry with self-recovery to protect the device from damage during over-current conditions. Proprietary circuitry effectively suppresses pop-and-click noise.
