Understanding the load presented by the reference pin of SAR ADCs is key when designing dataacquisition systems with low harmonic distortion.The internal circuitry connected to the reference pin of most successive-approximationregister analog-to-digital converters (SAR ADCs) (and some wideband delta-sigma ADCs) consists of switched-capacitor loads. During the conversion process, a switched-capacitor load imposes a current demand that can cause the external system’s reference-output voltage to fluctuate in time. Consequently, the SAR ADC reference-pin voltage also fluctuates.

谐波的定义谐波:是指对周期性非正弦交流量进行傅里叶级数分解所得到的大于基波频率整数倍的各次分量,通常称为高次谐波。简单来说,谐波就是频率是工频(50HZ)整数倍的分量。

Selecting an analog switch with a minimum THD requires one with low on-resistance (RON) and consequently low on-resistance flatness (RFLAT(ON))。 Some analog-switch data sheets neglect to specify flatness, but it can be assumed to be approximately 10% of the on-resistance. Flatness is defined as the difference between the maximum and minimum values of on-resistance as measured over the specified analog-signal range.
