PAM8945-EV, Evaluation Board based on PAM8945 High Efficiency Class-G Audio Power Amplifier

Descripción

• PAM8945-EV, Evaluation Board for the PAM8945 is a high efficiency Class-G audio power amplifier with an integrated boost converter. It drives up to 4W (10% THD+N) into an 4O speaker. With 85% typical efficiency, the PAM8945 helps extend battery life when playing audio. The built-in boost converter generates the voltage rail for the output stage. This provides a louder audio output than a stand-alone amplifier connected directly to the battery. It also maintains a consistent loudness, regardless of battery voltage. The PAM8945 features battery tracking AGC function which adjusts the Class-D gain to limit battery current at lower battery voltage
