LA4282
Audio Power Amplifier
Class AB, 10W × 2-Channel
Overview
The LA4282 is the IC for 2-channel SE power amplifier that is developed for
TVs and monitors audio system. High power and low distortion are realized.
This IC incorporate various functions (muting function, and various protection
circuit) necessary for audio system.
Features
High-power 2-channel AF power amplifier
Low distortion
Minimum number of external parts required (no bootstrap capacitor
required)
Low pop noise at the time of power supply ON/OFF
Good ripple rejection (58dB typ)
Wide operating voltage range
External muting available
On-chip protector against abnormality (thermal shutdown, overvoltage)
Typical Applications
Home Stereo
TV
