¹For specified performance, headroom requirement is 1 V.

²Temperature range: −40°C to +125°C, typical at +25°C.

³External reference means 2 V to 2.85 V with overrange and 2 V to 3 V without overrange.

⁴Integral nonlinearity error is specified at 4 LSB (minimum/maximum) for 0 V to 16 V and 0 V to 20 V ranges with V_REFIN= 2.5 V external reference, and for all ranges

with V_REFIN= 2 V to 2.85 V with overrange and 2 V to 3 V without overrange.

⁵Guaranteed by design and characterization, not production tested.
