3CH, 2.2W, Class-D Audio Power Amplifier
PT2002
DESCRIPTION
The PT2002 is a Class-D power amplifier designed for audio equipments, maximum output power can
reach up to 2.2W x 3CH (VDD = 5V, RL = 4Ω, THD = 10%). The PT2002 composed of exclusively
designed Class-D circuitry (patented) by PTC, along with the most advanced semi-conductor
technology. Compare with traditional Class-AB amplifiers, the PT2002 performs much better power
efficiency (>80%), less heat dissipation, and produces superior audio quality. External circuitry is very
simple and flexible, 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.
