1 For specified performance, headroom requirement is 1 V.
2 Temperature range: −40°C to +125°C, typical at +25°C.
3 External reference means 2 V to 2.85 V with overrange and 2 V to 3 V without overrange.
4 Integral nonlinearity error is specified at ±4 LSB (minimum/maximum) for 0 V to 16 V and 0 V to 20 V ranges with VREFIN = 2.5 V external reference, and for all ranges
with VREFIN = 2 V to 2.85 V with overrange and 2 V to 3 V without overrange.
5 Guaranteed by design and characterization, not production tested.
