LA4425PV
Overview
The LA4425PV is a 5W power amplifier with very few external parts. Encapsulated in a surface mount package
[SSOP44K (275 mil)], it is designed for operation without a heat sink. Only two external parts (Only IN/OUT coupling
capacitors). Almost no evaluation, adjustment and check of its functions as a power IC required, enabling control to be
simplified and set patterns to be further miniaturized.
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
