• RE: Interfacing ADAU1701 with AD1955

    Thank you for reviewing my spec Brett.

    Meanwhile I have chosen the ADG3308 instead of the ADG3304 because the A-side Input High Voltage (Min) spec for the 3308 is 0.65xVcca as opposed to Vcca-0.4 for the ADG3304. This means that with the ADG3304 the…

  • RE: impedance configuration for ADG3304 Level translator

    Hello FEB,

    I'm using ADG3304 too, and I have a similar issue.

    The A-side of the ADG3304 is directly connected to a BF506F output pulled up with 10kOhm, while Y-side is connected to a logic port (74HC...).

    The BF506F drives the ADG3304 with a square…

  • ADG3304-EP and using it to translate and connect to multiple SPI devices


    I am trying to use two ADG3304-EP connected with two AD5141W, on the same SPI bus going to an FPGA.

    My concern is due to the fowling sentences from the ADG3304 datasheet -

    When the application requires level translation between a micro - processor…

  • ADG3304 - I2C

    Is it possible to use the ADG3304 for I2C level translating (3,3V Master, 5V slave)?

  • RE: ADG3304 with logic level switch

    Hi MMat370,

    Kindly check again the ADG3304 datasheet on page 17. It was mentioned that:

    For proper operation of the ADG3304, the voltage applied to the VCCA must be less than or equal to the voltage applied to VCCY.

    I think you got the opposite?


  • Bidirectional, logic level translator  for I2C.


    Can ADG3304 use for level translator of  I2C interface?.

    The datasheet describes only for SPI and Microwire.


    It would be greatly appreciated if advice could…

  • Questions About Using the ADG3304

      Good morning.  I have a customer experiencing a problem with a SPI bus that is going through ADG3304s for level translation.  The bus works fine before they activate the power domain which contains the ADG3304s at which point the bus get very messy and…

  • ADG3304/8 Input driving requirements


    ADG3304 and ADG3308 is same architecture device, I believe.

    I found different description in datasheet.

    ADG3304 data sheet requests lower output impedance <=150ohm / 36mA peak current capability for output driver.

    ADG3308 data sheet doesn't…

  • RE: Problem using ADG3304 as level shifter for SPI with Arduino

    Hi Federico,

    You mentioned:

    "Is the Arduino max driving current (40mA) too close to the 36 mA required by the level translator?"

    Can you check if the Arduino (5V) really provides 40mA current to the ADG3304? We need to be sure that Arduino…
