Diodes Inc. PAM8009 3W Stereo Class-D Audio Amplifiers are designed for driving bridged-tied (BTL) stereo speakers. Included is a stereo SE (Headphone) amplifier. The PAM8009 is packaged in two power efficient packages and provides excellent audio performance and numerous features to provide complete system flexibility. Advanced DC volume control minimizes required external components and allows precise volume control with 64 steps over the range of +20dB to -60dB. Mute and standby modes are provided to reduce noise or to minimize power.
