Description: AD779x 系列产品常见问题解答AD7798/AD7799均为适合高精度测量应用的低功耗、低噪声、完整模拟前端，内置一个低噪声16位/24位Σ-Δ型ADC，其中含有3个差分模拟输入，还集成了片内低噪声仪表放大器，因而可直接输入小信号。当增益设置为64、更新速率为4.17Hz时，AD7799的均方根（RMS）噪声为27nV，AD7798的均方根（RMS）噪声为40nV.-AD779x products FAQ AD7798/AD7799 are high-precision measurement applications for low-power, low noise, complete analog front-end, built a low-noise 16-bit/24-type Σ-Δ ADC, which contains three differential analog input, but also integrated chip low-noise instrumentation amplifier, which can directly enter the small-signal. When the gain is set to 64, update rate for 4.17Hz when, AD7799 the RMS (RMS) noise of 27nV, AD7798 the RMS (RMS) noise 40nV.
