Part Number: INA111
Hi,When verifying the INA111 circuit, an output overshoot was observed at the time of pulse input.Please tell me the conditions under which overshoot is likely to occur and the conditions under which overshoot is difficult to converge with respect to pulse input.・Input signal : 6kHz (Pulse width : 26.6μs)Could you give me your advice?Best regards,Yusuke
overshot is likely to occur at very low gain. Here's a snippet from the datasheet of INA111:
Another cause for overshot is capacitive output loading.
Can you show a schematic of your circuit?
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to kai klaas69:
Thanks Kai for the reply.
As Kai is indicated, the overshoot is likely caused at lower instr. amplifier gains.
We will reply to your specific question, if you are able to enclose a schematic. I have replied your other inquiry, the overshoot is likely caused by the Q in the INA111 at lower gains. Since I do not know the INA111's output load, I am unable to comment on it.
