3W ANTI-CLIP CLASS-D AUDIO POWER AMPLIFIER

DESCRIPTION

FEATURES

A2331 is a 3-W (V_DD=5.0V, R_L=4Ω) high efficiency

filter-free class-D audio power amplifier in a wafer

chip scale package.



Output Power

-3.0W (V_DD=5.0V, R_L=4Ω, THD+N=10%)

-1.8W (V_DD=5.0V, R_L=8Ω, THD+N=10%)

Four mode can be selected with CTRL

terminal: Anti-Clip 1, Anti-Clip 2, Anti-Clip off,

Power-Down

A2331 has a ꢀProfessional Anti-Clip output control

circuitꢁ which reducing distortion of output signal

due to either the over level input signal or power

supply voltage down with battery.



Low THD+N and Low Noise

Low EMI

Features like high efficiency, −80dB PSRR, over

current protection and thermal protection function

make the A2331 ideal for cellular handsets.

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

The A2331 is available in CSP9 package.
