• ADG3245 leakage

    Hi,

    I am using STM32F401RE microprocessor to implement SPI.

    CLK rate is 1.5MHz.

    I try to use ADG3247/ADG3245 for translate 3.3V to 1.8V.

    It seems that there is a leakage between the bits. If I use the CLK input on A0 and nothing on A1 input, at the…

  • How does ADG3245 working?

     ADG3245 can change 2.5V  to  1.8V it is allow bidirectional signals,

    so my question is ,

    1, if signal comes from  1.8V  side ,  to ADG3245  the output is connected to 2.5V side.

    can this working good?

    2, When VCC=2.5V   SEL=2.5V  BE=0   in this mode it makes 2.5…

  • ADG3245 for SPI and I2C

    Hello all,

    I'm working on a project in which I use two types of digital potentiometers (AD5254(I2C), and AD5235(SPI)). The potentiometers have the supply voltages of (VDD: +2.5V, VSS: -2.5V). And I use a microcontroller that's supplied by 3.3V…

  • ADG3245 package question - [LFCSP] (CP-20) package

    The ADG3245 level shifter shows an exposed thermal pad for the 20-Lead Lead Frame Chip Scale Package [LFCSP] (CP-20) package.

     

    Can I tie the thermal pad to ground?

     

     

    I apologize if this is the wrong forum. I could not figure out where else…

    I just ran across this, and wanted to point out that there might be a related thread regarding the ADG3245.  See ADG3245 for SPI and I2C 

  • RE: ADG3245B

    Hi AGXIN,

    May I ask, why do you call the ADG3245 as buffer? I'd like to clarify first how would you want to use the ADG3245 before I answer your questions. May I know your application? What is your expected output? Please take note that the ADG3245 is…

  • Bus Enable on ADG chips

    What voltage do the BE bus enable (active low) pins need to be set to when not active low?

    The SEL pin is specified what voltage it needs but not this pin. I've looked across data sheets on multiple level translators to try and figure this out.

    The ADG324x family are level translators that is capable of translating voltage levels from high to low only. This statement can be supported by the Truth Tables and is further discussed at the Mixed Voltage Operation, Level Translation Section of the…
