LA6570 ^{Monolithic Linear IC}
5CH Driver (BTL : 4CH, H-Bridge : 1CH) for CD
Overview
The LA6570 is a 5CH driver (BTL : 4CH, H-bridge : 1CH) for CD players.
Features
• Built-in POWER AMP 5CH (bridge connection (BTL) : 4CH, H-bridge : 1CH)
• IO max 1A
• Built-in level shift circuit (Except H-bridge.)
• Built-in MUTE circuit (output ON/OFF).
(Operates only for CH1 to CH4 BTL AMP. No operation for H-bridge and 5VREG.)
• Built-in 5V regulator (with external PNP transistor)
• Implements VREF switching function (Select H for external, or L for internal (2.5 V))
• Built-in overheat protection circuit (Thermal shutdown)
