Product Change Notification
The ONA10IV is a digital input, mono Class−D audio amplifier with real time, integrated current and voltage sensing of the loudspeaker it’s driving. This sense data is transmitted to the host through a separate digital output to enable a smart amplifier system.
The ONA10IV can be directly connected to a 2−cell (2S) or 3−cell (3S) battery and offers a fast automatic gain control (AGC) for brownout protection that can react within 10 µs.
Up to eight devices can share the digital audio interface through I2C control. A separate bus (MAGC) is used to synchronize gain across multiple ONA10IV instantiations during a brownout protection event.
