Description
The AW87304 is a Mono Class-D audio amplifier. With a quiescent current of 0.95mA at 3.7V, it extends battery life in portable applications. Its 19V ultra-low noise floor and low distortion ensure clean listening. It can deliver 1.8W output power into a 8 speaker at 10% THD+N.
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.
AW87304 is available in a WLCSP 0.98X0.98-9B package.
