SANYO LA4601 Datasheet
Ordering number : EN6013
LA4601
Monolithic Linear IC
LA4601
Audio Power Amplifier for
Radio Cassette Recorders
Overview
This is a different-package version of the power
amplifier LA4600 with ultralow peripheral
component count. Basic power supply spec is Vcc
= 15V, but a 9V spec for operation without
heatsink is also possible. BS capacitor, NF
capacitor, and oscillation-stopping CR components
are incorporated into the IC circuitry .
Functions
• Pin compatible with the LA4600
• Heatsink not required for 9V version
• Output power VCC =15V/3Ω....7.0W X 2
• Built-in stanby switching
• Built-in overheat protection (TSD)
