在50Hz交流mV信号放大中,相同放大倍数,相同外围电路下,AD8422到3.6mV时输出信号就开始不再正弦,AD8429到6mV后输出信号才发生变形,这是什么差别导致的呢。

Hi nicolai.sidenius@icloud.com,
I haven't actually tried paralleling multiple amplifiers to reduce the noise, though, we have a great article about the advantage of paralleling amplifiers to increase SNR performance here: (https://www.analog.com/en…
Hi,
I use AD8429 in my current measurement circuit. Schematic is attached for your reference. This is a current measurement circuit. Current flow through R-sense resistor and AD8429 amplifies this differential signal. AD8429 positive supply is 10V and…
AD8429单电源供电时,输入和输出范围是受限的,下图是用INAMP在线仿真工具仿真出来的。可以看出输入共模太低了,您可以试试太高共模,现在是2.5V,抬高到5V试试(去掉R4,R13电阻)https://tools.analog.com/en/diamond/#difL=-0.1&difR=0.1&difSl=0.1&gain=10.67&l=2.5&pr=AD8429&r=2.5&sl=2.5&tab=1&ty=2&vn=0&vp=12&vr=6…
I have the evaluation board EVAL-INAMP-82RZ for AD8429. The gain resistor Rg = 6.3 Ohm. Ideally I would like to get a low-noise amplifier for the Barkhausen coil in the range from 1 to 70 kHz.
I tried two variants from the AD8429 datasheet - 1) Figure…
