Hi Kiwiki,
The noise gain at low frequency ranges will not necessarily be 0dB. It is dictated by Rf and Rg values (NG at low frequency = 20*log[1+Rf/Rg]).
I suspect that the input common mode resistance and Rf is what is causing the NG above 0dB. You…
Hello Nick,
Sorry for my late answer but I was abroad with limited access.
Not here but in another windows.
I tried to install other library from TI and it works. I ll try to uninstall the software and any link with OPA380 and try again.
Thanks you for…
Part Number: OPA380 Other Parts Discussed in Thread: OPA381 , OPA379 After installing TI PSPICE the TIA OPA380 appeared to not be part of the standard TI library ...
However, after downloading the PSPICE model from the product folder, I discovered the…
Part Number: OPA380 Hi,
I wanted to work on OPA380 in my lab and got confused with the internal circuit given in datasheet.
I can somehow make out that bottom opamp is taking voltage of pin 2 and applying a high-pass filtering at 2.3Khz and then a low…
Part Number: OPA380 Hi,
I was studying about transimpedance amp and came accross this IC. In the datasheet, there is a circuit which is intriguing me.
On the first page I came across this circuit which, as per my knowledge, is a simple transimpedance…
Part Number: OPA380 Other Parts Discussed in Thread: OPA830 , OPA817 Hi Experts,
We are wondering if this transimpedance op-amp performs differential amplification for a low input impedance signal? We are planning to use it with bipolar electrode.
Would…
Part Number: OPA380 Other Parts Discussed in Thread: TINA-TI Hi,
I am trying to run a simulation of the OPA380 in PSpice for TI. I downloaded the OPA380 spice model from the TI website (OPA380 PSpice Model (Rev. B)). The spice model also comes with a…
Part Number: OPA380 Hi Guys,
Good day. We need your help to check our customer's concern.
I have attached OPA380 TIA circuitry that was used in two cases from our customer. Kindly review the circuit.
Currently they are using the OPA380(single-side power…
Part Number: OPA380 Hi, Good day. Our customer is looking for the thermal information (JC and JB) for the OPA380AIDGKR. Can you please help us provide this information? Thank you. Regards, Cedrick
Part Number: OPA380 has anyone got a circuit for a transimpedance amplifier for use with a photomultiplier giving a negative output current. I should probably be able to work this out but my Texas amplifier knowledge is a bit limited :(
