• RE: ADM1293 GENERATING AN ALERT

    Hi Ren

    I saw ADM1293 form intel CRB platform. that is why I asking for 20us limitation. so all the GPO1/GPO2 of ADM1293 cant response in 20us.

  • ADM1293 I2C hold time

    Dear Sir,

             ADM1293 has support internal hold time of at least 300ns? If yes, the master provide 0ns to 299ns internal delay is ok? ADM1293 report data to master can measure the hold time of at least 300ns? Thanks!

  • ADM1293 Delta Power negative issue

    Hi Sir,

            Please help check below formula is correct?

    "delta_power = [Accumulated_power(n) + (rollover_count(n) * 2^15)] - [Accumulated_power(n-1) + (rollover_count(n-1) * 2^15)]"

    Because use (Data 2 - Data 1) and (Data 8 - Data 7) the delta_power…

  • RE: Power Metering SoC

    I agree with LucaV that the ADM1293 is what you need.

    with auxiliary power supply it can monitor voltages down to 1V.

    the product has just been released and the product page is being updated at the moment.

  • RE: What are the min and max sample rates for the ADM1293-1 over temperature?

    Brad,

    We use the LTC2946 for higher voltage applications, but it doesn't work down at FPGA I/O and core voltage levels (0.95V to 1.8V).  It has poor resolution at low voltages, compared to the ADM1293 in the lower voltage settings.  Another consideration…

  • RE: High side current measurement

    Hi Htek,

        There are probably several dozen different ways to do this. Since you want to receive the value in digital form, I suggest that you use one of our high side current monitors. Take a look at these:

    LTC4151 High voltage I2C voltage and current…

  • adm1278/93

    the two device interface is PM-Bus,

      1. can the two device be controlled ( accessed) by i2c master ?

            from the experiment i had, it works by i2c master.

      2. from "1", does it means the two device is i2c compatible ?

      3. from Data Sheet…
