ST92F124/F150/F250 - ELECTRICAL CHARACTERISTICS
10-BIT ADC CHARACTERISTICS
Subject to general operating conditions for VDD, fOSC, and TA, unless otherwise specified.
Figure 161. Typical Application with ADC
Notes:
1. Unless otherwise specified, typical data is based on TA=25°C and VDD-VSS=5V. These values are given only as design
guidelines and are not tested.
2. VAIN may exceed AVSS or AVDD. However the conversion result in these cases will be 0000h or FFC0h respectively.
3. Any external serial impedance will downgrade the ADC accuracy (especially for resistance greater than 10 k
Ω). Data
based on characterization results, not tested in production.
4. Value guaranteed by design.
