PT5326

PT5326 2.0 W/CH Stereo Filter-free Class-D Audio Power Amplifier GENERAL DESCRIPTION The PT5326 is a dual 2.0W high efficiency filterless class D audio power amplifier in a 4mm×4mm QFN-16 and SMD-16 or SOP16 package that requires only five external components. The PT5326 uses Class D architecture, the device delivers up to 2.0W while offering up to 80% efficiency. The PT5326 offers a spread-spectrum PWM modulation scheme that reduces EMI-radiated emissions due to the modulation frequency. The device utilizes a fully differential architecture, a full bridged output, and comprehensive click-and-pop suppression. The PT5326 features high 60dB PSRR, low 0.11% THD+N. Thermal-overload protection prevents the device from being damaged during a fault condition. The PT5326 is ideal for cellular handsets and PDA applications.
