Description

The AW87306DNR is a Stereo Class-D audio amplifier. With a quiescent current of 2.0mA at 3.7V, it extends battery life in portable applications. Its 29μV ultra-low noise floor and low distortion ensure clean listening. The amplifier offers five configurable gain settings controlled via a dedicated gain selection pin. Integrated spread spectrum modulation and edge-rate limiting reduces EMI while reducing the size and cost of output filters. The amplifier offers Over-Current Protection, Over-Temperature Protection, Under-Voltage Protection to protect the device. The amplifier features click-and-pop suppression that reduces audible transients on startup and shutdown. AW87306 is available in a WBDFN 3X3-14L package.
