Part Number: THS3491RGTEVM Other Parts Discussed in Thread: THS3491
Hello Experts,
According to datasheet on page 4 (2.2) :
Desoldering the output matching resistor and replacing it with a single 50-Ω series output resistor that gives only 6-dB…
Part Number: THS3491RGTEVM Other Parts Discussed in Thread: THS3491 , THS3091 Tool/software: Hi, So I needed a buffer at 100MHz 200MHz and 300MHz which can give output voltage 20, 15, 10 respectively at those frequencies. THS3491 seems like the best fit…
Part Number: THS3491RGTEVM Other Parts Discussed in Thread: THS3491 HI TI forum,
I recently used this evaluation board to measure the frequency response of THS3491RGT when in A = 10V/V, using a range of Rf and Rg (feedback / gain resistors).
I used…
Hi Ahbib,
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 :-)

Hell there,
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…
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:
THS4303EVM
THS3491RGTEVM
Also, if you know of…
Hi Stefan,
have you read section 2.2 of the EVM manual?
www.ti.com/.../ths3491rgtevm
Maybe the resistors of the output resistor network have some manufacturing tolerances? For a small signal response measurement you could replace the output…
Hi Kai,
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.…
