TDA1514A是飞利浦开发的高性能、高保真音频功率放大集成电路,是为数字音频系统专门设计的,由于其特殊的全保护功能(过热保护、短路保护、功率管安全工作区保护、静电放电保护),以及独特的制造工艺(外形小、热阻极低、低失调电压、低谐波失真、低瞬态互调失真、高纹波抑制、噪声抑制、无电源开关时的喀嚓声),很适用于组合音响、CD唱机等高保真放音系统,当然倍受发烧友的推崇。一、极限和性能参数 TDA 1514A外形采用单列9脚直插封装,如图1所示,其中脚4与散热板相连。
The TDA1514A is a high-performance, high-fidelity audio power amplifier integrated circuit developed by Philips that is specifically designed for digital audio systems. Due to its special full protection features (overheat protection, short circuit protection, power tube safe working area protection, electrostatic discharge protection) , As well as unique manufacturing processes (small form factor, very low thermal resistance, low offset voltage, low harmonic distortion, low transient intermodulation distortion, high ripple rejection, noise suppression, click without power switch) In the combination of audio, CD players and other high-fidelity playback system, of course, much respected enthusiasts. First, the limit and performance parameters TDA 1514A shape with a single 9-pin in-line package, shown in Figure 1, where the foot 4 is connected with the cooling plate.
