LA4425A
Monolithic Linear IC
5W Power Amplifier
with Very Few External Parts
for Car Radio and Car Stereo
http://onsemi.com
Overview
The LA4425A is a 5W power amplifier with very few external parts. The smallest package in the industry
[SIP-5H(TO-126 type)]. Only two external parts (Only I/O coupling capacitors). Almost no evaluation, adjustment and
check of its functions as a power IC required and simplified control
Functions
• Wide operation supply range → 5 to 16V
• On-chip protection:
- Over-voltage protection
- Thermal protection
- Output D.C. short protection .
• On-chip pop noise reducing circuit
