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…
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…
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 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…
