LA6543M
4-Channel Bridge (BTL) Driver for CD-ROM
Overview
The LA6543M is a 4-channel bridge (BTL) driver
developed for CD-ROM applications.
Functions
• 4-channel power amplifier with bridge circuit (BTL)
• IO max: 1A
• Integrated muting circuit (MUTE: Output OFF at Low,
output ON at High. MUTE1 is for channel 1, and MUTE2
for channels 2, 3 and 4.)
• Integrated thermal shutdown circuit
• Divided output stage power supply (VS1: CH1, CH2, CH3;
VS2: CH4)
