• 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…

  • ADAS1000-1 Amplifier and Filter

    Hello, 

    My question is concerning the ADAS1000-1. There are certain electrode input ranges usually from 0.3V to 1.6V I believe. Does that mean we would need to implement an amplifier before sending the ECG signal to the ADAS? Just because an ECG signal…

  • LTC3785-1 PGOOD

    Hi,

    I am in the process of upgrading my LTC3785 design to use the LTC3785-1 variant so that I can take advantage of the PGOOD signal. 

    Can you please confirm if the maximum voltage of this pin is 6V.  This seems a little low for an Open Drain connection…

  • Differential video transmission with ADA4433-1 and ADA4830-1

    Hello,


    Thanks for providing the spice model of both ADA4433-1 and the ADA4830(-1).

    I'm trying to design a DC coupled differential transmission system using the ADA4433-1 and the ADA4830.

    The overall gain from input (ADA4433-1) to output (ADA4830…

  • RE: ADATE305 VDDO_0/1, VSSO_0/1 termination

    Hi katsu,

       The supply pins you mentioned above are still connected internally to the supplies of the ADATE305. They should still be shorted to VDD and VSS respectively. The reason for their special mention on the datasheet was so the user can pay special…

  • RE: HMC666_using IF pin without 1:1 transformer

    Hi Josh,

    IF port could be used as single ended but the conversion loss will be 3dB more than specified in datasheet, and the isolation maybe worse.

  • How to configure 1 TX-1 RX in No-OS

    Hi all,

        My design uses ADFMCOMMS2 module and ZEDBOARD, I want to transmit data using 1 TX- 1 RX but the default set 2  TX-2RX in No-OS, so what parameters in  default_init_param in main.c file I need to modify in order to  set 1 TX- 1 RX, thank you for…

  • ADA4627-1 and ADA4637-1 Null Inputs Connection

    Hi,

    ADA4627-1 and ADA4637-1 have NULL pins which are offset adjust pins. If I do not plan to use offset adjust what should I do with the NULL pins? Leave it floating or use 100k Ohm pull-up resistors?

    Regards,
