Hello,

VREFINT is specified as 1.224V +/-20mV with VDD = 3.0V.

Is there any information available on the accuracy when VDD = 1.8V?

Any guidance welcome!!

Kentxu.

I guess there's not alot of action in this forum... :(

If anyone is interested, I've had a reply from ST:

''

Vrefint = 1.224 +/-20mV is guaranteed by characterization on the whole suplly range from 1.65 V to 3.6 V.

''

So that's good news for these parts.
