About SARADC input range

[YaKu_1055906]

Hi all,

I have a question about SARADC input range of CY8C4247LTI-L475.

I will use the single end mode of SARADC.

The setting of SARADC is as follows.

---------------------------------------------------------------------

Vref select: Internal 1.024 volts, bypassed

Single ended negative input: Vref

Single ended mode range: 0.0 to 2*Vref(2.048V)

---------------------------------------------------------------------

I'd like to know the analog signal input range.

Does PSoC4 break when analog signal exceeding 2.048V is input?

(VDDA is 5V or 3.3V.)

Best regards.

Yasu

No, your PSoC will not break when the input on any pin is smaller than VDDA and larger than 0V. Nonetheless the conversion result might not be what you expect when the input is larger than 2.048V
