Monolithic Linear IC
For CD Players and Recorders
LA6548ND
Four-Channel Driver IC
Overview
The LA6548ND is a four-channel driver IC for CD players and recorders (four BTL amplifier channels).
Functions
• Four BTL connection power amplifier channels
• I max 0.7A
O
• Built-in level shifters
• Muting circuit (on/off control of all outputs)
(This circuit applies to the BTL amplifier circuits. It does not control operation of the regulator.)
• Built-in regulator (provides a 3.3V output using an external pnp transistor)
• Thermal protection circuit (thermal shutdown circuit)
