Part Number: OPA3S2859-EP
Hello,
This is my first time posting in this forum. I am attempting to design a high-speed transimpedance amplifier circuit using the schematic provided in the datasheet. However, after assembling all the components, the circuit…
Hello Peter,
Great timing on your end! I actually just had my last discussion with the team members I have been working with.
There are two conclusive points of interest for you:
1) You can leave the highest gain setting path un-terminated/no-connect…
Part Number: OPA3S2859-EP Other Parts Discussed in Thread: OPA3S2859 , OPA859 Hello, What is the input current-noise specification for the OPA3S2859? We were unable to locate it in the datasheet and want to understand it's contribution to the overall system…
Part Number: OPA3S2859 Hello team,
Is there any MIN / MAX data for on resistance of OPA3S2859?
On the datasheet, I could only find TYP value.
Best Regards,

Part Number: OPA3S2859-EP Other Parts Discussed in Thread: ADS52J65 , OPA855-Q1 , OPA3S2859 Dear Support team,
While reading through the OPA3S2859-EP datasheet, I did not see specs included for second and third order harmonic distortion (HD2/HD3) and was…
Part Number: OPA3S2859 Hello team,
Do you have simulation model for OPA3S2859? I could not find it on TI.com.
The simulation model for pspice or TINA is preferred, but any simulation model is welcome.
Best Regards,
Kei Kuwahara
Part Number: OPA3S2859-EP Page 1 of the datasheet shows the OPA3S2850 used as transimpedance amplifier with a photo diode connected at the COM_A input and hence allowing the selection of LO, MID and HI gain by programming the internal switches. So far…
Part Number: OPA3S2859 Other Parts Discussed in Thread: ADS1285 , , REF5025 , REF7025 Our application is a ratiometric one, where the signal of interest is Sample/Reference. We need to connect to photodiodes where the ratio of the two varies over a large…
Part Number: OPA3S2859-EP Other Parts Discussed in Thread: OPA3S2859 , TINA-TI Hi,
I have built the board according ref design. 10k, 100k branches work as expected but 1k branch oscillates at 80 MHz.
If I input 500 kHz current I have this signal
thanks…
Part Number: OPA3S2859 Other Parts Discussed in Thread: OPA3S328 , OPA2380 Hi All,
I have a customer who is working on a laser detector and the first stage of the process is a TIA circuit, for which they have expressed interest in leveraging the OPA3S2859…
