PT2001 제품 세부 정보

DESCRIPTION
The PT2001 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 PT2001 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 PT2001’s has a much higher efficiency (>85%), low heat dissipation, and produces superior audio quality. PT2001’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 input for improved CMRR.
• Maximum output power 2.2W (4Ω) x 2 @ THD=10%
• Operating on Both BTL (Bridged Tight Loaded) and SE (Single Ended) configuration
• No LC filter needed when driving speakers in BTL configuration.
• Driving 32Ω headphone on SE configuration.
• Highly Improved PSRR (>70dB) for powered from noisy PC-BUS power.
• Automatic gain-reduced during headphone attached to the amplifier.
• Shutdown function
• POP noiseless in shutdown and power ON/OFF period
• Built-in short circuit protection
• Built-in overheat protection
• High efficiency (8Ω load>85%), low heat dissipation
• TSSOP 20 pins miniature packages for saving PCB size.

APPLICATIONS
• Portable media player
• Portable DVD player
• LCD monitor
• Small multimedia speakers
• Hand-free phone
• Laptop
• Other audio applications
