LA6545M
Four-Channel Bridge (BTL) Driver for CD-ROM
Overview
The LA6545M is a 4-channel bridge (BTL) driver
developed for use in CD-ROM systems.
Functions
• Bridge connected (BTL) four-channel power amplifier
• V_CE (residual voltage) minimized (channels 1 and 2) by
using two power supplies.
• I_Omax: 1.0 A
• Muting circuit provided (output on/off control)

(MUTE pin: low for output off, high for output on.
MUTE1: controls channels 1, 2, and 3, MUTE2:
controls channel 4.)
• Thermal protection (shutdown) circuit
• Separated output stage power supply (VS1: channels 1
and 2, VS2: channels 3 and 4)
