• RE: Negative and positive voltages with LTC1403

    If you can use the LTC1403-1, an easy solution is to use a fully differential amplifier like the ADA4945 between your filter circuit and the ADC input. Use the same +/-3V supplies for the ADA4945. Use figure 104 of the ADA4945 data sheet and connect VOCM…

  • RE: .file_attr 1="1";

    Hi, Thanks for replying. I had tried the "-no-auto-attrs" with no improvement. The same error reappears elsewhere if I delete the source file causing the problem. It also occurs in the standard "BF609_init" project, so I have attached those files. The…

  • LTC2942-1


    The Sense+ pin is connected to both Charger and Load. So,I would like to know how the LTC2942 could determine the operation mode between charge and discharge.


  • RE: LTC3785-1 PGOOD

    Hi- Yes, abs max is 6V. The UV and OV thresholds are different.

  • ADA4530-1 bias current

    The datasheet says + - 20fA gauranted

    however the datasheet rev B page 17 shows statistical data spreading way outside this for both inputs, in fact the plot states the standard deviation is about 20fA.

    Which is correct ?

    I see other people were querying…

  • Cell Balancing with LTC6812-1

    Hi everyone,

    I am trying to implement passive cell balancing with using external discharge circuit. As I read the datasheet of LTC6812-1 we need to configure DCC bit for the cell we want to discharge. 

    I looked into the configuration register group A and…

  • ad7768-1


    I want to use the AD7768-1 with 5V AVDD1 = Vref and 3,3V VDDIO.
    In demo-circuits the AVDD2 is connected to probably noisy VDDIO!
    Wouldn't it be better to supply AVDD2 from 5V over a R-C-Filter, that would lower the voltage to around 3V?


  • ADA4941-1

    Hi All,
    I am looking for OPAMP which can convert single ended signal to differential signal to drive the ADC which has differential input. I have selected ADA4941-1 and tested for -2 and +2 gain configurations which are mentioned in Figure 58 and Figure…
  • AD5755-1 Communication

    Hello I am having trouble communicate with this chip I have the address pin set to AD1 = 1  ADO = 0.  I know I am suppose to send a command NOP  command to read from the desire register.

    I am sending the command in this format:

    command = AD5755_WRITE_CMD…

  • ADA4666-1 with Photodiode

    Hello Together,

    should this combination of a ADA4666-2 and a ADC-converter work?
