LA6576

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.
