Other Parts Discussed in Thread: TIDA-00725 , OPA857 , THS4541 , LMH6629 , ONET2591TA hi,
Does TI has recommendation for 1ns pulse laser driver design?
Need TIA design that works with 10nA to 1MA PhotoDetector Current.
I found the TIDA-00725 TI ref design…
Hello,
If you are not getting the desired gain at 120 MHz then it probably means that the amplifier closed -loop bandwidth is < 120 MHz. How is the customer measuring the performance at 120 MHz...with a sine wave input?
Like you mentioned we need…
Hello Mickey,
Q1- He tests the OUT pin(8 pin) voltage and the OUTN pin(5 pin) voltage of U6 in the schematic. But they are in phase: This is not possible, the OUTN pin will always stay constant at 1.833V or (5/9)*Vcc.If you are seeing the OUTN pin actually…
Hello!
I'm designing a PCB in Altium Designer 16 using the THS4541 FDA. However, this component is not (yet) in the Altium Vaults (there are a lot of THS45xx parts, but not this one).
I've found a reference design in TI's website which makes use of…
Hello Shyam,
We have been using a real photodiode to test the performance of our amplifiers in a TIA configuration recently. We excite it with a pulsed laser diode and use an optical attenuator to control the incident power on the photodiode.
See the…
