LA6542M
4-Channel Bridge (BTL) Driver for CD-ROM
Overview
The LA6542M is a 4-channel bridge (BTL) driver
developed for CD-ROM applications.
Functions
• 4-channel power amplifier with bridge circuit (BTL)
• IOmax: 1A
• Integrated muting circuit
(MUTE: Output OFF at Low, output ON at High.
MUTE1 is for channels 1 and 2, and MUTE2 for
channels 3 and 4.)
• Slew rate 0.5 V/µs
• Integrated thermal shutdown circuit
