Part Number: TIDA-00978 Other Parts Discussed in Thread: OPA857 Hello;
I have a question.
Can I use this design for a Avalanche Photodiode?
İs there any complication for this usage?
Part Number: TIDA-00978 In my tests, when the voltage of D1-pin2 exceed 24V, the output voltage of OPA857-pin8 will be 0V, why? All of the devices have not been destroyed. W hen I decrease the voltage, the PCB can return to normal(the output DC voltage…
Part Number: TIDA-00978 I am evaluating TIDA-00978 in test mode with a photodiode soldered in the appropriate position. After exposing the Photodiode to LED(running on DC current), I could not find any change in the output. I have followed instructions…
Part Number: TIDA-00978 Other Parts Discussed in Thread: OPA857 Hi,
I am evaluating TIDA 00978 module. Right now, I am setting up the test mode for this EVB. A sine wave(100 KHz, 500mV peak-to-peak) generated from Tektronix AWG is sent through a Tee…
Part Number: TIDA-00978 Hi, I am trying to evaluate TIDA-00978 EVB. As per the reference manual, i have set up the connections for Test_mode. I was unable to detect any signal from the output pins.
For the experiment, I have generated a Sine wave from…
Hello Amar,
OPA857EVM-978 is the same as reference design TIDA-00978. The product folder of the reference design is here: https://www.ti.com/tool/TIDA-00978
Gerber Files and BOM can be found in the product folder of the reference design under Design…
Hello Jakub,
Sorry about the confusion, attached is the step file for the board. The OPA857EVM-978 is the same board as our reference design TIDA-00978. You will find all the design files on the reference design page.

Hello,
In the TIDA-00663 we have used a different photodiode than the one you have selected so we did not need to extend the OPA857 transimpedence bandwidth.
Regarding the specific question to the OPA857 and the TIDA-00978 I would suggest you to post…
