• RE: Using LT3092 with a DAC

    Good job getting yourself some hardware to test yourself.  You will learn a lot about these clever devices.  I think you can answer most of your questions yourself if you read the LT3092 datasheet and understand how the LT3092 works.  If you do that you…

  • RE: The Current of VCCS by LT3083 is not stable !

    I want to know why LT3083 didn't perform as well  as LT3092 ?

  • RE: Pulse Current Use LTC3092

    The image below of a LT3092 datasheet graph shows that the LT3092 is too slow to make a 1 ns edge since the LT3092 takes around 500ns to respond to a transient on the input supply, and the ~500ns response time is a very rough indication of the regulation…

  • LT3092 output minimum current

    LT3092 is used to excite the ICP vibration sensor. The current output current is set at 150uA. According to the manual, the minimum output current is 0.5mA.Will it damage the chip?If this is not appropriate, what is the recommended constant current source…

  • LT3092 - improving latency to have faster voltage rise slopes

    I have a serial string of 6 LT3092, each set to deliver 10mA. This serial string is feeding a zner stack with 6 zeners each rated for 33V. So the total volatge across the zener stack when it goes into breakdown is 198V. I have a DC source (230V, 0.1A…

  • LT3092: Problem with supporting BJT for higher current

    Dear Analog-Team,

    I am having troubles using the LT3092 current source with a BJT as current amplification device. 

    It behaves very strange.

    My goal is this: I want to controll current from V2 from 0 to about 2Amps by setting V1 (in reality it is an…

  • RE: lt3092 dosen't prfrom like as the simulation (LTspice) predict

    I performed a test similar to yours in the lab and my results show that an LT3092 programmed for 1mA does not hold 1mA when charging a 200pF capacitor as the capacitor voltage slews from 0V up towards the 10V rail.  My setup was simpler than yours - I…

  • LTC6268-10 output oscillating

    Hi engineer :

     The scheme is as follows:

    Then I test the J11 signal.The J10 is not connect anything.

    But the waveform is like this.What are wrong.The input or the power?

    Then can I use LT3092 to test the TIA circuit.

    Connect J3 to TIA's J10.Looking…
