Table 32-95. Accuracy characteristics.
Notes: 1. Maximum numbers are based on characterisation and not tested in production, and valid for 5% to 95% input voltage range.
2. Unless otherwise noted all linearity, offset and gain error numbers are valid under the condition that external V
REF
is used.
