Preliminary
PT2332
DESCRIPTION
The PT2332 is a CLASS-D power amplifier designed for audio equipments, maximum output power
can reach up to 2.2W x 2 (VDD = 5V, RL = 4, THD = 10%). The PT2332 composed of exclusively
designed CLASS-D circuitry (patented) by PTC, along with the most advanced semi-conductor
technology. When compared to the traditional CLASS-AB amplifiers, the PT2332’s has a much higher
efficiency (> 80%), low heat dissipation, and produces superior audio quality. PT2332’s external
circuitry is simple and easily accessible, and consists of flawless self-protection capabilities. The
chip’s packaging is small, thus it occupies an insignificant amount of space on the circuit board;
therefore, making it the predominant choice when it comes to audio amplifiers.
