LMK1D2104: Disabled Current Draw

IDK

Part Number: LMK1D2104
Other Parts Discussed in Thread: LMK1D1208

Tool/software:

Hello,

How much current does the LMK1D2104 draw when all outputs are disabled using the EN pin? This does not seem to be listed in the datasheet.

Thanks,
Matthew

Hi Matthew,

Sorry for the delay. I began soldering the LMK1D2104 onto the evaluation module for the LMK1D1208. I will disable the outputs and measure the current. I will then count up the number of pull-up/pull-down resistors, determine their current consumption, subtract that from the total, and derive the current consumption of the LMK1D2104.

Expect an answer by the end of the week.

Thanks,

Michael

Hi Matthew,

Sorry for the delay, after doing some board rework, I have found that the LMK1D2104 consumes 50.402 mA with its outputs disabled.

Thanks,

Michael
