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)
