PT2366L 1W Class-AB Audio Power Amplifier DESCRIPTION PT2366L is an audio power amplifier IC utilizing advanced CMOS technology. It can deliver 1W power output under 5V supply voltage. The power consumption is very low in stand-by mode. Built-in over-temperature protection, package size is not occupies PCB space. It is suitable for small or portable products. FEATURES • • • • • CMOS technology Output power 1W (8Ω) Low harmonics distortion Built-in pop and click noise suppress Shutdown function, turn on can into save mode (Icc<0.1µA) • Built-in over-temperature protection APPLICATIONS • • • • • DSC, PDA LCD TV or Monitor Electronic dictionary Multimedia speaker Other A/V applications BLOCK DIAGRAM Tel: 886-66296288‧Fax: 886-29174598‧ http://www.princeton.com.tw‧2F, 233-1, Baociao Road, Sindian, Taipei 23145, Taiwan PT2366L APPLICATION CIRCUIT SINGLE ENDED INPUT Notes: 1. * = Not stuffed 2. Add a circuit (Cf) if needed, it can be a low filter to delete high frequency oscillation, but must to avoid incorrect Rf and Cf combination to cause “glide” before 20KHz. In general Rf=20KΩ, Cf=25pF, -3dB is 320KHz is recommended.
