PT2830
10W Stereo Integrated Audio Amplifier
DESCRIPTION
FEATURES
The PT2830 is an integrated audio amplifier design for
the compact audio system; the maximum output power
is up to 10W x 2. Utilizing PTC exclusive, patented
Class-D modulation circuit, compare with traditional
Class-AB amplifier, the PT2830 have a lot of benefit for
high efficiency, low heat dissipation and very low
harmonic distortion.
