Overview
Ordering number : EN7742 LA6576 Monolithic Linear IC 5-channel Driver for Compact Disk Applications Overview The LA6576 is a 5-channel driver for optical disc drives with a VREF switching function.
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 CH1 to 4 and not operable for the H bridge of 5VREG) • 5V regulator built-in (external PNP transistor).
• With VREF changeover function (H: external, L: internal).
• Overheat protection circuit (thermal shutdown) built-in.
