OUT
tolerance is typically ±20%.
Note 3:
Min/max range guaranteed by gain-error test. Operation outside min/max limits will result in degraded performance.
Note 4:
Reference input resistance is code dependent, minimum at 8554 hex.
Note 5:
Slew-rate value is measured from 0% to 63%.
Note 6:
Guaranteed by design. Not production tested.
