PAM8106 Green 10W Stereo Class-D Audio Power Amplifier With NCPL & SSM Description Pin Assignments The PAM8106 is a 10W/CH stereo class-D audio amplifier with Spread-Spectrum modulation, which offers high-quality low THD+N, low EMI, and high PSRR. 32 31 30 29 28 27 26 25 PAM8106 runs off of a 4.5V to 15V supply with high efficiency up to 24 NC 1 NC 92% to eliminate the heat-sink. With advanced EMI suppression by RINN 23 SD 2 Spread-Spectrum Modulation (SSM) technology, PAM8106 requires 22 AVCC only inexpensive ferrite bead filters for audio outputs while meeting RINP 3 EMC requirements for overall system cost reduction. 21 VCLAMP 4 MUTE PAM8106 20 AGND 5 AVDD XXXYWWLL PAM8106 integrates Non-Clipping Power Limit (NCPL) technology 6 19 V2P5 LINP which adjusts the gain and eliminate the output signal clip due to the 18 PL 7 LINN over-level input signal. PAM8106 also offers low THD+N and protects SSMCTL 17 NC 8 NC the speaker from damage. 11 13 16 12 14 15 9 10 PAM8106 is fully protected against faults with short circuit protection and thermal shutdown as well as undervoltage and DC input protection. The PAM8106 is available in a W-QFN5050-32 (Standard) package.
