Green PAM8106
10W Stereo Class-D Audio Power Amplifier With NCPL & SSM
Description
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.
Pin Assignments
PAM8106 runs off of a 4.5V to 15V supply with high efficiency up to
92% to eliminate the heat-sink. With advanced EMI suppression by
Spread-Spectrum Modulation (SSM) technology, PAM8106 requires
only inexpensive ferrite bead filters for audio outputs while meeting
EMC requirements for overall system cost reduction.
PAM8106 integrates Non-Clipping Power Limit (NCPL) technology
which adjusts the gain and eliminate the output signal clip due to the
over-level input signal. PAM8106 also offers low THD+N and protects
the speaker from damage.
PAM8106 is fully protected against faults with short circuit protection
and thermal shutdown as well as undervoltage and DC input
protection.
