It can support as low as 23mA idle loss current using standard LC filter configurations. It is integrated with 90-mΩ MOSFET that allows output currents up to 7.5 A. The high efficiency allows the amplifier to provide an excellent audio performance without the requirement for a bulky heat sink. The device can be configured for either master or slave operation by using the SYNC pin. Configuring using the SYNC pin helps to prevent audible beats noise. 7.2 Functional Block Diagram |
