please show your latest schematic. And please post a photo which shows your modifications carried out on the EVM board.
Maybe you have damaged the OPAmp during experimenting? Then check again with a fresh one :-)
Part Number: THS3491RGTEVM Other Parts Discussed in Thread: THS3217 , THS3491
I have a THS3491RGTEVM and want to use it to amplify 20-40M square wave to 10Vpp (with input up to 1Vpp). I can get the waveform amplified to 10Vpp with a gain of…
As you said, I built the same circuit with THS3491RGTEVM and the thin board. The Rf of both of them are 300Ω. While EVM is stable and thin board is not. So I think there is two possible scenarios to explain why the thin board is instable.…
Part Number: THS4303 Other Parts Discussed in Thread: THS3491RGTEVM , THS3491 Hi Team,
I would like to request please, if possible, to receive the gerber files for the following evaluation boards:
Also, if you know of any product…
have you read section 2.2 of the EVM manual?
Maybe the resistors of the output resistor network have some manufacturing tolerances? For a small signal response measurement you could replace the output resistor…
