tolerance is typically ±20%.
Min/max range guaranteed by gain-error test. Operation outside min/max limits will result in degraded performance.
Reference input resistance is code dependent, minimum at 8554 hex.
Slew-rate value is measured from 0% to 63%.
Guaranteed by design. Not production tested.
