AD674B Supply current ICC IEE on standby and initial mode

Dear Sir,

Our customer is using AD674B and would like to check the ICC and IEE current when chip in below status. Could you please help to check?

1. Standby mode

2. only Power on. not in conversion mode.

3. After initial.

    Hi YenChen,

                  There was no much information on the current of the AD674 datasheet on the condition you mentioned, unlike the latest ADCs, these parameters are shown. I'll have to check the actual setup for this.  Would you know the application that the customer is using and Would they also prefer some of the latest ADCs in the portfolio? If you can enumerate what they are looking for in an ADC, I can shortlist ADCs that they can use in their application.

    Regards,

    Jonathan

  • Hi Jonathan,

    Sorry, This product is the old model for customer and they can't change the parts. Now they have some problem on AD674 and would like to clarify below 3 item's (ICC and IEE current). Could you please help us to check this question? 

    1. Standby mode

    2. only Power on. not in conversion mode.

    3. After initial. 

  • Dear Sir,

    Could you please help us to check this question again? Because our customer  is waiting for our feedback. Thanks.

    Hi YenChen,

          I got a chance to have a quick measurement on the device. Typically the current will be: The said conditions will have almost the same results. Is there a particular concern in your application, on why these values are of concern? What is your application by the way?

    1. Icc = 5mA

    2. Ilogic = 3mA

    3. IEE = 10mA

    Regards,
