PAM8009

ADVANCED INFORMATION PAM8009 3W STEREO CLASS-D Audio Amplifier and Class AB Headphone Driver (DC VOLUME, UVP and AGC Function) PAM8009 XXXYWWLL Description The PAM8009 is a 3W, Class D audio-power amplifier for driving bridged-tied stereo speakers. Advanced DC volume control minimizes external components and allows BTL (Speaker) volume control and SE (Headphone) volume control, the gain range is from +20dB (Volume=5V) to -60dB (Volume=0V) with 64 steps precise control. Pin Assignments Integrated power-limit technology suppresses the output signal clip automatically due to the over level input signal. This technology also offers low THD+N and protects speaker. Integrated Undervoltage Protection (UVP) technology, external undervoltage detection can be used to shut down the PAM8009 before an input device can generate a pop. PAM8009 is available in SO-24 and U-QFN4040-20. Features Operating Voltage: 2.8v ~ 5.5v Filter – Free and Low EMI Low Quiescent Current IDD=7mA @ VDD= 5V 64 Steps DC Volume Control from -80dB to +20dB by DC Voltage with Hysteresis Power Limit Function Disable: 0.45VDD ~ VDD Max. Power: GND UVP Function Disable: Floating Output Power @ THD+N=1% BTL Mode VDD=5V, Rl=4Ω; Po=2.4W VDD=5V, Rl=8Ω; Po=1.4W SE Mode VDD=5V, Rl=32Ω; Po=60mW Output Power @ THD+N = 10% BTL Mode VDD=5V, Rl=4Ω; Po=3.0W VDD=5V, Rl=8Ω; Po=1.7W Input Signal and Headphone Output Signal in Phase Thermal and Over-Current Protections with Auto-Recovery Power Enhance ...
