DN494 - 驱动一个低噪声、低失真18位、1.6Msps ADC
<div>
LTC®2379-18 是一款 18 位、1.6Msps SAR ADC，具有极高的 SNR (101dB) 和 THD (–120dB)。该器件还具有一种独特的数字增益压缩功能，因而免除了在 ADC驱动器电路中增设一个负电源的需要。<br />

模拟转换器性能不只依赖分辨率规格</p>
<p>
大量的模数转换器(ADC)使人们难以选择最适合某种特定应用的ADC器件。工程师们选择ADC时，通常只注重位数、信噪比(SNR)、谐波性能，但是其它规格也同样重要。本文将介绍ADC器件最易受到忽视的九项规格，并说明它们是如何影响ADC性能的。</p>
