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
