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.
FEATURES
• CMOS Technology
• Stereo differential analogue input
• Maximum output power 2.2W(4Ω) × 2 @ THD=10%
• Output low-pass LC filter is not necessary
• Preset 2 voltage gain selection (20dB and 26dB)
• Contains shutdown function
• POP noise free in shutdown changed and power ON/OFF period
• Built-in short circuit protection
• Built-in overheat protection
• Low harmonic distortion (0.1%), superior sound quality
• High efficiency (8Ω load > 85%), low heat dissipation
• SOP-16 pins and SSOP-16 pins, miniature packages
APPLICATIONS
• Portable Media Player
• Portable DVD Player
• LCD Monitor
• Small multimedia speakers
• Hand-free phone
• Laptop
• Other audio applications
