EUA6204A
3W Mono Fully Differential
Audio Power Amplifier
DESCRIPTION
The EUA6204A is a mono fully-differential audio
amplifier, capable of delivering 3W of continuous
average power to an 3BTL load with less than 10%
distortion (THD+N) from a 5V power supply, and
720mW to a 8load from a 3.6V power supply.
The EUA6204A is ideal for PDA/notebook and portable
devices application due to features such as -80-dB
supply voltage rejection from 20Ha to 2kHz, improved
RF rectification immunity, and a fast startup with
minimal pop.
The EUA6204A is available in a SOP-8(FD).
FEATURES
z Supply Voltage 2.5V to 5.5V
z 2.3W into 3from a 5-V Supply at THD=1% (typ)
3W into 3at THD=10%
z Low Supply Current: 4mA typ at 5V
z Shutdown Current: 0.01µA typ
z Fast Startup with Minimal Pop
z Only Three External Components
- Improved PSRR (-80dB) for Direct Battery Operation
- Full Differential Design Reduces RF Rectification
- -63dB CMRR Eliminates Two Input Coupling
Capacitors
z RoHS Compliant and 100% Lead (Pb)-Free
Typical Application Circuit
APPLICATIONS
z PDAs
z Portable Devices
z Notebook
