LMV602: LM602

user6145121

Part Number: LMV602
Other Parts Discussed in Thread: OPA2320

我们需要使用LMV602做一个buffert用来加在示波器探头前面，测量板上的信号；需求：

高输入阻抗，电阻

低寄生电容，电容；

但是从TI的datasheet里我们只能看到bias input current;

请问，/1、是否就是用Vcc/bias input current= input 电阻？

2、输入的寄生电容多少呢？数据手册没有介绍。

Hi,

the OPA2320 seems to be a very good alternative :-)

Thanks for your recommendation. I noticed that in OPA2320, the input capacitor is about 4~5pf;

So do you have that data of LMV602, since I have the LMV602 in hand now.

No, I do not have the input capacitance specifications of LMV602. But let's see what the PSPICE models say:

Without warranty :-)
