Note 1: Gain Error tested at VREF = 2.0V, 2.5V, and 3.0V.

Note 2: ROUT 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.
