The PAM8904EGPR is an advanced class-D driver architecture that drives ceramic/piezo sounders with high output voltage. By utilizing an integrated boost converter, it can generate a peak-to-peak output voltage significantly higher than the input supply voltage, allowing for robust audio performance even from a single-cell Li-ion battery.

Its low-power shutdown mode and efficient internal switching frequency make it highly suitable for mobile electronics, medical devices, and industrial alerts. The driver also includes automatic shutdown and wake-up features to maximize battery life.
