• 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 Gideon,

    Sorry for the delay in responding.

    The cause of the problem is "-file-attr CORE0" and "-DCORE0" both being included on the compiler command-line. Could you delete CORE0 from the "Additional attributes" in Tools Settings > CrossCore Blackfin…

  • ad7768-1

    Hello,

    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?

    Additionally…

  • 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…

  • LTC7000-1 SNS bypassing

    Is it possible to bypass the current protection by shorting the  SNS+ and SNS- pins together with a trace?

    Thanks

  • ADA4945-1 THD behavior

    Hello,

    I used the ADA4945-1 as ADC front-end (LTC2380-24) with supply rails centered
    to ADC 2.5V Vref ( Vcc= +7.5 / Vee = -2.5V for 10V total supply).

    The FDA is configured as fully differential filter, with 2 cutoff frequencies.
    2 small relays allow…

  • Question with regards to ADA4530-1

    Hi , 

    I have a number of questions with regard to ADA4350-1. 

    We are planning to get EVAL-CN0407 evaluation board to evaluate ADA4350-1.

    I cannot see EVAL-CN0407-1-SDPZ board in buy list, is it possible to order only EVAL-CN0407-1-SDPZ for replacement.

    Is…

  • ADA4530-1 humidity effects

    Hi,

    I was wondering if there is any data available for the input voltage offset of an AD4530-1 versus change in %RH?

    The datasheet specifies an input bias current error when the %RH changes, but nothing on input voltage offset.

    kind regards,

    David

  • Composite amplifier using ADA4637-1 and ADA4870-1

    I want to build a composite amplifier using the Figure 77 of the datasheet ADA4870-1. It says that the voltage offset is less than 500 uV. I simulate this circuit using LTSpice, when driving ada4637-1 with 0V and monitor the output of ADA4870-1, it is…
