• Question about ADN2830

    In the ADN2830 data sheet, we know that current sink mode is the the factory default configuration.  if we use this mode, Should the IBMON pins  be  connected  to the ground in the Fig 2 and Fig3 in the datasheet ???  I think it is not necessary 'cause IBMON…

  • ADN2830: Monitor photodiode

    Our laser diode has a monitor photo diode with 1439.554 uA for maximum laser
    output power.However, your Continuous wave laser average power controller
    ADN2830 accepts Monitor Photodiode currents from 50ua to 1200uA.How can I

  • ADN2830 MPD current

    For ADN2830, I would like to get the detailed transfer functions between IMPD
    and IBIAS. I found there was only the simple description  stated in the
    datasheet. Would you pls give the exact transfer function between them?

  • ADN2830 huge interference signal after power up

    Good Day,

           We've used ADN2830  with our CW laser control project. We parallel three ADN2830, use negtive power supply just  refer to AN655.

    Now we can drive the laser sucessfully, however, hugh interference signal be tested with ADN2830 each PIN,…

  • ADN2830 Laser Diode Controller

    I have spun a board for the ADN2830 to control a JDSU laser with internal photo detector. The good news is both the cathode and anode
    are isolated from the case. I'm using two in master/slave as I need about 300ma Id. Currently I have a Si rectifier for…

  • ADN2830输入信号

    尊敬的工程师您好:

         我们目前正在寻找一种激光驱动器可以100MHz正弦波+直流偏置的方式调制激光二极管,同时需要芯片具备APC功能,从ADN2830的数据手册中得知ADN2830可以进行连续波调制且具有APC功能,但是数据手册中并没有标明可接收的输入信号频率范围。请问ADN2830是否可以在这么高频率的信号下工作,另外此芯片是否可以直接驱动P型激光二极管。如果不可以是否有其他芯片可供选择。

  • Current precision of ADN2830

    Hi,

    I have 2 questions regarding ADN2830, TEC Controller IC.

    1. What is the current (or power) precision of the output power of the ADN2830? Like how precisely it can be varied (like 1microAmps/10microAmps).

    2. Is it possible to control the PSET pin with…

  • ADN2830 Monitor Photodiode Current

    Dear Sir,

    While using ADN2830, we found the PD current from laser  is lager than 2000 uA. However, the photodiode current

    ADN2830 can receieved is less than 1200uA. Than, how can we use the ADN2830 to driver this laser?

  • Current stability of ADN2830?

    Hi everyone,

    Does anyone know what the current stability is of the power controller ADN2830, when operating to control constant current, rather than constant power?

    Here is my application:  We'd like to use an ADN2830 eval board as a current controller…

  • ADN2830的ALS功能

    ADI专家您好!

    在ADN2830的datasheet中,关于ALS功能有以下这段:

    AUTOMATIC LASER SHUTDOWN

    When ALS is logic high, the bias current is turned off. Correct operation of ALS can be confirmed by the fail alarm being raised when ALS is asserted.

    从字面上理解ALS,就是“自动激光关闭”;但是从上面描述文字来看…
