Kinetis KL02 : Analog input absolute maximum rating

koichisakagami — Fri, 10 Apr 2015 08:13:18 GMT

Dear community,

We are checking the device parameters for designing a custom board.

[Background]
In the Data Sheet, Voltage and current operating ratings Tables,
it is described that
VDD [Digital supply vaoltage] -0.3(Min.) -- 3.8(Max.)
VIO [IO pin input voltage] -0.3(Min.) -- VDD + 0.3(Max.)

[Question]
How much voltage is the Analog input absolute maximum rating ?
Is it identical to VIO voltage ?

Best Regards,
Koichi Sakagami

Hi, Koichi

Sorry for the late reply,

If you are using the analog pin in the ADC the input voltage should be between VREFL(-100mV - 100mV ) and VREFH (min 1.13v - max 3.6v), if you are using CMP or DAC the input voltage should be MIN VSS-0.3V -- MAX VDD (1.71V - 3.6V)

You can check more information about the Analog Input electrical specifications in section 3.6 of the datasheet

Hope it helps,

Regards!

Patricia
