Smart amplifier allows for richer and louder audio for next-gen smartphones
- Louder and clearer audio: Offers 5.7-W output power into 4 Ω and 3.8 W into 8 Ω at 4.2 V.
- Low idle-channel noise (ICN) simplifies designs: 15.9-µV ICN eliminates audible speaker noise when using the smartphone in a receiver or pause mode and also eliminates the need for external components.
- Integrated multilevel Class-H boost converter and automatic gain control: Dynamically adjusting audio output during periods of low battery voltage maximizes battery life. User-specified boost control helps customize boost on/off based on end-equipment power profile requirements.
- Reduces development time: Use any processor with an I2S output to enable on-chip speaker protection. This greatly reduces porting and integration time, enabling end equipment manufacturers to get to market faster.
