PT2332

2.2W×2 Class-D Audio Power Amplifier Tel:886-2-66296288 Fax:886-2-29174598 URL:http://www.princeton.com.tw 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 = 4Ω, 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.
