PT2004 Product details

DESCRIPTION
The PT2004 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 PT2004 composed of exclusively designed CLASS-D circuitry (patented) by PTC, along with the most advanced semi-conductor fabricate technology. When compared to the traditional CLASS-AB amplifiers, the PT2004’s shows much higher efficiency (> 80%), low heat dissipation, and also performs superior audio quality.
The PT2004’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.
