ONA10IVGEVB: 16 Watt Digital Input Class-D Audio Amplifier with Speaker Sense Digital Output

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 via a dedicated digital output. 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[1]μs. A separate single-wire bus (MAGC) can be used to automatically synchronize gain changes across multiple ONA10IV instantiations during a brownout protection event. Device-configurable I2C slave addressing allows up to eight devices to share the same digital audio interface bus.
