图1AD7192内部结构图
TheAD7192 is a low noise, complete analog front end for high precision measurement applications. It contains a low noise,24-bit sigma-delta (Σ-Δ) analog-to-digital converter (ADC).The on-chip low noise gain stage means that signals of small amplitude can be interfaced directly to the ADC.
