LA6571
Monolithic Linear IC
5CH Driver for Mini Disk and Compact Disk
http://onsemi.com
Overview
The LA6571 is 5-channel driver for mini disk and compact disk applications (BTL-AMP: 5CH).
Features
• Power amplifier 5-channel built-in.
• IO max 1A
• Level shift circuit built-in.
• Mute circuit (output ON/OFF) with three built-in channels (2-2-1).
(Operates independently for each of MUTE1: CH1 and 2, MUTE2: CH3 and 4, and MUTE3: CH5.
Not operating for the regulator (REG))
• Regulator (REG) built-in (external PNP transistor).
Voltage setting (typ: 1.5V or more) with an external resistor
• Overheat protection circuit (thermal shutdown) built-in.
