Hi,
I just brought a BUF634 to separate my power source and load and when I tested the buffer I found that when I connected a 100 Ohm resistor as the load, the gain was only 0.1. However, when I use a 20 kOhm resistor (nearly open) the gain was 1. My connection follows figure 19 in the datasheet (shown as below, Rs=50 Ohm) except I directly connected the BW pin to -V rail. My input was a DC power source of 10 V. Is there anything wrong with my connection?
The second question is about the maximum inrush current and voltage that the buffer can endure? Say, I have an inductive load and when switching off there will be back emf and current go through the output of the buffer. I am going to use MOV to suppress the back emf.
