ONA10IV 16 Watt Digital Input Class-D Audio Amplifier with Speaker Sense Digital Output www.onsemi.com Description The ONA10IV is a digital input, mono ClassD audio amplifier with real time, integrated current and voltage sensing of the loudspeaker its driving. This sense data is transmitted to the host through a separate digital output. The ONA10IV can be directly connected to a 2cell (2S) or 3cell (3S) battery and offers a fast automatic gain control (AGC) for brownout protection that can react within 10 s. WLCSP30 Up to eight devices can share the digital audio interfaces through CASE 567VB 2 I C control. A separate bus (MAGC) is used to synchronize gain across multiple ONA10IV instantiations during a brownout protection MARKING DIAGRAM event.
