LA6569 5-channel Driver for Compact Disk
Applications
Overview
The LA6569 is a 5-channel driver for optical disc drives that includes a regulator on/off circuit.
Features
• Power amplifier 5-channel built-in. (Bridge-connection (BTL) : 4-channel, H bridge : 1-channel)
• IO max 1A.
• Level shift circuit built-in (except H bridge).
• Mute circuit (output ON/OFF) built-in.
(Operable with BTL AMP with MUTE1 : CH1 and MUTE2 : CH2 to 4 and not operable for the H bridge of 3.3VREG.)
• 3.3V regulator built-in (external PNP transistor).
• With a function to set the loading output voltage.
• Overheat protection circuit (thermal shutdown) built-in.
• Regulator ON/OFF circuit built-in.
