ADA4817-1， AD8615 ， AD8616，AD8066， AD8067， 都可以参考一下
Dear Eng. Dr. Art Kalb we appreciate your comprehensive reply related to ADA4898
Now we have several questions related to Equations (4-6) from the specification datasheet of ADA4817-1/4817…
Hi,My customers are considering using ADA 4817-1, but I got a question.
#1 Is a graph of input bias current and temperature change prepared?
Can you lower your transimpedance gain and then take more gain in a 2nd stage? I don't know what your photodiode characteristics are, but using a the photodiode wizard, I was able to come up with this circuit:
That had this response:
Sorry for this late response.
The Application Note (AN232) you sighted refers to JFET-input amplifiers that operate on high voltages and have relatively high input capacitance. The ADA4817 has a maximum supply voltage of 10 V that is far…
Hello, I asked the original question. We built the system, and found the following:
1. When the PD is activated the ADA4817 output goes to -V with what appears to be an approx. 600uA current sink. As the output voltage is varied by the other amp in the…
(low noise and low distortion application)
I want to buffer a small signal with ADA4817 and then send the output signal through a 50 Ohm coax cable. I put a series 50 Ohm resistor at the output of ADA4817. the cable's length is 1 meter.
