PAM8606
6W Stereo Class-D Audio Power Amplifier with DC Volume Control
Key Features
General Description
n 6W@10%THD / Channel Output into a 8Ω
www.datasheLeto4ua.cdoamt 10V
n Low Noise: –80dB
n Over 90% Efficiency
n 32Step DC Volume Control from -75dB to 32dB
n With Shutdown/Mute/Fade Function
n Over Current , Thermal and Short-Circuit
Protection
n Low THD+N
n Low Quiescent Current
n Pop Noise suppression
n Small Package Outlines:
48pinTQFP(E-PAD) 7mm*7mm Package
n Pb-Free Package (RoHS Compliant)
The PAM8606 is 6W (per channel), stereo class-
D audio amplifier with DC Volume Control which
offers low THD+N (0.1%), low EMI, and good
PSRR, allowing it to produce high-quality sound
reproduction. The 32 steps DC volume control
has a +32dB to -75dB range.
The PAM8606 runs off of a 7.0V to 13.5V supply
at much higher efficiency than class-AB
amplifier.
The PAM8606 only requires minimal number of
external components, resulting in significant
cost and board space savings.
Applications
n Flat Monitor /LCD TVS
n Multi-media Speaker System
n DVD Players, Game Machines
n Boom Box
n Music Instruments
The PAM8606 is available in a 48pin TQFP(E-
PAD) 7mm*7mm package.

Notes
1. The AP AUX-0025 low pass filter is necessary for every class-D amplifier measurement
with AP analyzer.
2. Two 22µH inductors are used in series with load resistor to emulate the small speaker for
efficiency measurement.
