Part Number: TIDA-00725 We are interested in TI’s developed OTDR solution TIDA-00725. We have gone through the document TIDUAZ1 but we have not been able to find the following basic and important OTDR parameters. Kindly let us know what values of…
Part Number: TIDA-00725
I am trying to build a laser range finder based on the APD and its biasing circuit and amplification circuit in TIDA-00725. The APD biasing circuit design is not clear to me.
Why I did not see an APD temperature monitoring circuit…
Part Number: OPA857EVM Other Parts Discussed in Thread: OPA857 , TIDA-00725 , Tool/software: TI-RTOS Hi
Is there anyway to test the functionality of signal chain circuit before connecting it to photodiode. I mean which signal should I feed to this board…
Hello CSC,
For specifically laser drivers/modulators, we have reference designs for very low frequencies intended to drive LEDs, and we have a very high frequency reference design for optical network communication which would be overkill for this application…
Other Parts Discussed in Thread: OPA857 , THS4541 , TIDA-00725 , TIDA-00978 , ADC34J45 , ADC32J45 hello to everyone,
I am currently using a fast transipendance amplifier based on OPA857 (20KOhm gain setting) and an Hamamatsu PIN diode S5973 0.8pF@5V. I think…
Hello Burak,
1) Are you saying you want to bypass the TIA? You would need a way to convert the current input source to a voltage which is best done by an amplifier configured in a transimpedance manner. Not sure about the detection speed for the MCU…
Part Number: OPA857 Other Parts Discussed in Thread: TIDA-00725 , , THS4541 , THS4508 I am looking for a suitable low noise, low distortion 20 V/V post amplifier for OPA857 TIA. In my application, the bandwidth is around 100 MHz. The TIDA-00725 reference…
Part Number: OPA857EVM Other Parts Discussed in Thread: TIDA-00725 Tool/software: TI-RTOS Hi,
I am using TIDA-00725 Signal-Chain Circuit, can anybody please tell me what is value of R28 in BOM?

Other Parts Discussed in Thread: THS4541 Dear Sir/Madam,
I am looking for design suggestion for OTDR as per block and spec below:
I have actually look at TIDA-00725 www.ti.com/lit/ug/tiduaz1/tiduaz1.pdf but I am not sure if it can cover the required wavelength…
