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.

FEATURES

• CMOS technology

• 3 channels, differential analog input

• Maximum output power 2.2W(4Ω) x 3CH @ THD=10%

• No external LC low-pass filter required

• 20dB fixed voltage gain

• Contains shutdown function

• POP noise free during shutdown and power ON/OFF period

• User adjustable power-on delay timing

• Built-in short circuit protection

• Built-in overheat protection

• Low distortion (0.3%)

• High efficiency (>85%, 8Ω load), low heat dissipation

• SSOP 24 pins, 173 mil body width miniature packages

APPLICATIONS

• Small multimedia speakers

• Laptop

• LCD monitor

• Portable DVD player

• Portable Media player

• Other audio applications
