摘要
∑-Δ模数转换器由于造价低、精度高、性能稳定及使用方便等特点,越来越广泛地使用在一些高精度仪器仪表和测量设备中,介绍该转换器的基本原理,并重点举例介绍AD7708芯片的应用,该芯片是16bit模数转换器,与24bitAD7718引脚相同,可直接升级。
In many fields of measuring analog volume, ∑-Δ A/D converters are applied widely more and more because of its characteristics of low cost, high accuracy, stable performance and being used conveniently. The basic principle of ∑-Δ ADC is described. The application of ∑-Δ ADC AD7708 is introduced as an example. AD7708 is a kind of 16-bit ADC and its pins are same as 24 bit ADC AD7718, so it can be updated to 24 bit directly.
