No electronic load. Because the experimental equipment can provide 3A current at most, and the input power is far less than 400W required by the operation manual, I want to ask whether the board can not be started due to insufficient input power, so there…
Other Parts Discussed in Thread: DEM-OPA-SO-1A , LMH6702 上一小节从理论上分析了CFB运放负向输入端的分布电容的影响。大家可能觉得还是很空洞。下面将从实验结果来验证上面的理论。(我总是喜欢先从理论的角度分析一个问题,然后再用实验来验证。有了实验结果,会让理论更形象,也更让人记忆深刻)。
下面是工程师Michael Steffes用老的CFB运放做的实验结果。它在上一小节的输入电容的位置,分别用0.5pF和5pF的电容做的实验。当负相输入电容为5pF时…
Hi,
1.The application environment is Molecular electronics, so the current will change form fA to mA(10^-11A~ 10^-3A).
from the datasheet of LMP7721, the input bias current is ±20 fA at 25°C, it can meet the requirement .
2. we used OPA129 before…
Other Parts Discussed in Thread: OPA690 , DEM-OPA-SO-1A 工程师您好:我用OPA690实现了一个负电阻电路,在没有任何输入的情况下,给负电阻电路提供正负5V的供电电压,发现输出端的电压一会是3.773V,一会又变为-3.821V,这是什么原因呢? 在电路中反馈电阻R=46Ω,
