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, overcurrent 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.
