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 of…
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 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-bias…
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 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.

Part Number: TIDA-00663 Other Parts Discussed in Thread: OPA857 , TIDA-00978 Hello!
I'm going to use TIDA-00663 reference design to make the pulsed laser range finder. This design uses OPA857 transimpedance amplifier.
I use the avalanche photodiode…
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…
