Monolithic Linear IC
Audio Output for TV application
5W Monaural Power Amplifier
Overview
LA4225 is a 5W monaural power amplifier intended for television audio output.
This IC requires only two external components (capacitors) to construct amplifiers and is ideal for realizing substantial
cost reduction of electronic devices.
Functions
• 5W monaural power amplifier (VCC = 18V, RL = 8Ω)
• Full complement of protection circuits
Thermal shutdown protector on chip
Short between an output and DC protection circuit
• On-chip pop noise reduction circuit
