Other Parts Discussed in Thread: OPA846 Hi everybody,
I'm using an OPA846
for a transimpedance amplifier. I would like to simulate my system
using PSpice, but I get an error. I've tried to simulate it with other amplifier models and it works.

Part Number: TLV3603 Other Parts Discussed in Thread: LMH6559 , OPA846 Hi,
I have a pulse (38Mhz, 12ps) going through a TIA (OPA846) and then to a buffer (LMH6559), before going to some RC filters circuit to average out/amplify the voltage of the pulse…

Other Parts Discussed in Thread: OPA846 Hi Team,
A customer is looking for a part with an open-loop gain greater than 20dB or as high as it comes at 20MHz. with low noise of 1nV/RT-HZ or up to 2nV/RT-HZ.
Can you please help?
Regards,
Marvin
Part Number: OPA862 Other Parts Discussed in Thread: OPA855 , OPA846 OPA862 application includes photodiode amplifier. However, data sheet indicates an input bias of IB Input bias current, A1 = 3.1 µA. That seems unusually high for this sort of app. Is…
Hi Luis,
Vin would be 12V maximum, but typically 6V. So the max Vcm is around 12V.
Of course the BW should be the highest possible, but with 5Khz we should be good.
Fast switch is only needed to minimize voltage drop on 10 Ohm resistor. Typically…
Hello Ratul,
Thank you for reaching out. We have done similar setup in the lab without a photodiode or AC input current source. The method we use is highlighted below:
This is from a PowerPoint with more details attached below. Make sure that C1…
Hello Deepthi,
I apologize for delay in response. For the best method to test out TIA based device without a photodiode, I would suggest using a voltage source and add a couple passives at the input to the inverting pin of the amplifier with estimated…
