nRF51422 CWtest mode consumption current

[takin]

Hi

I use nRF51422 for our products. In a product line, we check the CWtest mode current consumption current.

I decided the determination value of the CWtest mode current consumption current with nRF51422 Product Specification. That indicates CWtest mode current consumption is 16mA@TX=4dBm.

But in a product line, the result is that current consumption is between 16mA and 18mA. Is the value within normal limit?

Would you tell me the upper limit of the current consumption.

Hi takin

I think what you measure is normal. The specification does not specify maximum value for the current consumption, but it specifies the numbers that we currently have. From what I have measured of current consumption myself, less than 20% variance from the expected value can be considered normal

Hi Stefan

Thank you for your answer. I got it.
