When will the industry-leading sub-femptoampere input bias current ADA4530-1 Electrometer Op Amp and pic oammeter board be releasing as a reference design?It already be 2017.

When will the industry-leading sub-femptoampere input bias current ADA4530-1 Electrometer Op Amp and pic oammeter board be releasing as a reference design? Isee the vidio that has been said  it will be releasing in 2017, but i can't wait any more since my programme needs this techology.Would you please give the PCB board or SCH? Thanks very much.

  • Hi,

    Thanks for your replying.

    My name is Zhentao. I brought the chip of ADA4530-I and ADA4530-1R-EBZ-TIA broad before . I choose ADA4530-1 to amplify current which is from photodiodes. My photodiodes are EOS S-025 and Hamamatsu S1337-1010BR. I also notice that your photodiode in the design example is hamamatsu S1226-18BQ. My temperature range is 800℃~3000℃. I chose ADA4530-1 as my amlifier since photodide circuit design wiard recommend.

    My lowest signal current level is pA and my current level range is from pA to uA. Maybe my data acquisition level is not so good. I use ADG1608 made by ADI or TX2/5V made by Panasonnic as switches, which  change the value of the feedback. The  feedback resistors include three different values, which are 1Mohm,100Mohm and 10Gohm. However, i found the result of the measuring accuracy is too bad. Maybe the reason is that amplifying circuit is effected by data acquisition circuit where I put two ciruits on the same board.

    Would you give me some advices to solve the problem? I'm appreciated for all your help.

    Thanks. Yours Zhentao.
