Figure 161. Typical Application with ADC
Notes:
1. Unless otherwise specified, typical data is based on T
guidelines and are not tested.
2. V
3. Any external serial impedance will downgrade the ADC accuracy (especially for resistance greater than 10 kΩ). Data
based on characterization results, not tested in production.
4. Value guaranteed by design.
