• LT3905 Sipm Design Review

    For biasing a SIPM (Silicon Photomultipliert, basically APD array) i need a low noise, low current DC Voltage in the range of 25 to 34Volts. Since Analog offers specific parts for apd supplies, i selected the LT3905 beaucse of the low output noise.

    I…

  • About LTpowerCAD library of LT3905

    Hi,
    Currently, LTpowerCAD does not support LT3905.
    Could you please provide the library of LT3905.

    If you have a question, please let me know.

    Best Regards,

    你好, 請問一下 :

    1. 關於LT3905  P.18的應用電路, 它的APD 輸出1mA 固定電流, 是怎麼計算/設定來的?

       這個1mA是可以經由設定調整的嗎? (如何設定.)

       為什麼電路裡的ILIM_MON和MON是short在一起?

    2. 在Adjustable APD bias裡, 使用CTRL做Vout Adjust, CTRL的最小輸入約幾V?   (目前有送電實測約0.12V, 再低就沒有輸出.)

    3. EVB : DC1956A 裡的R12=是634K, R13是15K…

  • LT3905 LDC - Boost DC/DC Converter with APD Current Monitor

    您好,我正使用LT3905APD提供电压。

    阅读手册后,有几点不明白:

    1. 根据手册,APD的阴极应连接LT39055脚(APD脚)。然而,应用APD时,APD的阴极还会连接TIA(运放搭建或者LTC6561等),此时我们希望APD产生的光电流流入TIA,我不明白APD的光电流到底流入LT3905ILIM_MONLOS_MONMON电流镜需要)还是TIA?如果流入TIA,ILIM_MONLOS_MONMON引脚如何工作?

    2. 根据我的使用需求,APD会产生5nsFWHM)脉冲光电流…

    nice meet you, about technical issue as below :

    1. about LT3905  Page.18 application circuit. its APD output current "1mA" , how to design or calculation?

       the "1mA" current, that can be adjusted?    how to adjust it?  

       why the circuit…

  • RE: Low noise SIPM design

    Hi,

    The LT3905 is a good candidate for your application.

    And, nn, I do not have a component I can recommend for CTRL control.

    Best Regards!
