日本飞利浦电子器件公司最近开发一种世界上最小封装、行业最高水平的低功耗音频数字式“TDA1545T”型D/A转换器。这种新型转换器采用该公司专利,称之为连续校准制的原理,在面积非常小(3.6mm~(-2))的触点上实现高精度的D/A转换。所谓连续校准制的D/A转换(通称CC—Dac),就是应用电荷守恒定律,在D/A转换电路里形成相当于LSB的非常稳定的电流源,并以这个
Japan’s Philips Electronics Company recently developed a world’s smallest package, the industry’s highest level of low-power audio digital “TDA1545T” type D / A converter. The new converter uses the company’s patent, called the principle of continuous calibration system, in the area of very small (3.6mm ~) contacts to achieve high-precision D / A conversion. The so-called continuous calibration system D / A conversion (commonly known as CC-Dac), is the application of the law of conservation of charge, in the D / A converter circuit is equivalent to the LSB is a very stable current source, and this
