LA4425A

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
