Supply Voltage 2.5V to 5.5V
The AAP6204 is a mono fully-differential audio
amplifier, capable of delivering 1.36W of continuous
average power to an 8Ω BTL load with less than 1%
distortion (THD+N) from a 5V power supply, and
720mW to a 8Ω load from a 3.6V power supply.
The AAP6204 is ideal for PDA/smart phone application
due to features such as -80-dB supply voltage rejection
from 70Hz to 2kHz, improved RF rectification immunity,
small 20mm2 PCB area, and a fast startup with minimal
pop.
1.36W into 8Ω from a 5-V Supply at THD=1% (typ)
Low Supply Current: 4mA typ at 5V
Shutdown Current: 0.01µA typ
Fast Startup with Minimal Pop
Only Three External Components
- Improved PSRR (-80dB) for Direct Battery Operation
- Full Differential Design Reduces RF Rectification
