15W STEREO CLASS-D AUDIO POWER AMPLIFIER WITH POWER LIMIT
Description
The PAM8006A is a 15W (per channel) stereo Class-D audio
amplifier which offers low THD+N (0.2%), low EMI and good PSRR
thus high quality sound reproduction.
The PAM8006A runs off of an 8V to 18V supply at much higher
efficiency than competitors’ Ics.
The PAM8006A only requires very few external components,
significantly saving cost and board space.
The PAM8006A is available in a QFN5x5-32L package.
