A2331
AUDIO AMPLIFIER
3W ANTI-CLIP CLASS-D
DESCRIPTION
FEATURES
A2331 is a 3-W (VDD=5.0V, RL=4Ω) high efficiency Output Power
filter-free class-D audio power amplifier in a wafer
3.0W (VDD=5.0V, RL=4Ω, THD+N=10%)
chip scale package (WLCSP).
1.8W (VDD=5.0V, RL=8Ω, THD+N=10%)
Four mode can be selected with CTRL
A2331 has a “Professional Anti-Clip output control
terminal: Anti-Clip 1, Anti-Clip 2, Anti-Clip off,
circuit” which reducing distortion of output signal
Power-Down
due to either the over level input signal or power Low THD+N and Low Noise
supply voltage down with battery.
Low EMI
Improved PSRR (−80dB) and Wide Supply
Features like high efficiency, −80dB PSRR, over
Voltage (2.5 V to 5.0V) Eliminates Need for a
current protection and thermal protection function
Voltage Regulator
make the A2331 ideal for cellular handsets.
Over-current and Thermal Protection function
Pop noise reduction function
The A2331 is available in CSP9 package.
Available in CSP9 package
