Description

• High-output dual-channel AF Power IC. (PO=6.0W×2, VCC=25V, RL=8Ω, f=1kHz, THD=1.0%)
• Low distortion (THD=0.1%, VCC=25V, RL=8Ω, f=1kHz, PO=2W).
• Minimum number of external parts requierd (no boot strap capacitor requierd).
• Low pop noise at the time of power switch ON/OFF.
• High ripple rejection (58dB typ).
• Wide supply voltage range (10V to 32V).
• On-chip protector against abnormality (thermal shutdown, overvoltage).

Absolute maximum ratings ( Ta=25°C )

1. Maximum supply voltage : Vcc = 35 V

2. Maximum output current : Io = 3.5 V

3. Allowable power dissipation : Pd = 20 W
