A2323
AUDIO AMPLIFIER
3W ANTI-CLIP CLASS-D AUDIO POWER AMPLIFIER
DESCRIPTION
FEATURES
A2323 is a 3-W (VDD=5.0V, RL=4Ω) high efficiency
filter-free class-D audio power amplifier .
A2323 has a “Professional Anti-Clip output control
circuit” which reducing distortion of output signal due
to either the over level input signal or power supply
voltage down with battery.
Features like high efficiency, −80dB PSRR, over-
current protection and thermal protection function
make the A2323 ideal for cellular handsets.
The A2323 is available in CSP9 package.
Output Power
3.0W (VDD=5.0V, RL =4Ω, THD+N=10%)
1.8W (VDD=5.0V, RL =8Ω, THD+N=10%)
Four mode can be selected with CTRL
terminal: Anti-Clip 1, Anti-Clip 2, Anti-Clip off,
Power-Down
Low THD+N and Low Noise
Low EMI
Improved PSRR (−80dB) and Wide Supply
Voltage (2.5 V to 5.0V) Eliminates Need for a
Voltage Regulator
Over-current and Thermal Protection function
Pop noise reduction function
Available in CSP9 Package
