ONA10IV 16W Class-D Audio Amplifier

onsemi ONA10IV 16W Class-D Audio Amplifier is a digital input, mono audio amplifier with real-time, integrated current and voltage sensing of the speaker it is 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 10µs. 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.
