AMC3301-Q1: AMC3301-Q1 Startup time and Typical current draw.

Part Number: AMC3301-Q1

Tool/software:

Hi,

I wondered if you have a typical (transient) startup time for the AMC3301-Q1 from application of the VDD input (3.3Vdc) to get to a stable output signal from the device?

Also, looking at the data sheet for the AMC3301-Q1, am I correct in thinking that the maximum VDD current draw is 42mA and a typical current draw should be around 28mA on the VDD pin if using a 3.3Vdc supply?

Kind regards

Michael

  • Hi Michael,

    It should typically be 1.6us.

    Yes, your understanding is correct. The current drawn will vary based on whether auxiliary circuitry is connected or not.

  • Hi Eva,

    The timing diagram looks like it is showing the transient time for the conversion from input (across the shunt) to the isolated output. I want to know what the time will be (from input to output) when power is applied to the device (so I am guessing a further delay of the isolated DC/DC SMPS starting up before the amplifier can produce an output proportional to the shunt current?

    Do you have any idea of this time?

    Kind regards

  • Hi Michael,

    That should typically be around 0.9ms:
