单片集成12～16位A-D转换器作为一种通用产品,已陆续出现在美国市场上。在视频图象上用的高速领域中,现以开发串并联式的产品为主;在音频和声频以及在低频用的高分辨率领域中,以开发△-Σ式的产品为主。其背景正处于数字信号处理普及的情况下。为了保证精度,还增加了自校正电路等产品。在低频、直流测量领域内,目前积分式A-D转换器仍在充当主角。
Monolithic integrated 12 to 16-bit A-D converter as a universal product, one after another in the United States market. In the field of high-speed video and video applications, the development of series-parallel products is the main focus; in the audio and audio and low-frequency high-resolution areas, the development of delta-sigma-based products. Its background is in the process of digital signal processing. In order to ensure accuracy, but also increased self-correcting circuit and other products. In the field of low frequency, direct current measurement, integrated A-D converter is still playing the leading role at present.
