1 Temperature range is as follows: B Version: 40°C to +85°C.
2 See the Terminology section.
3 Linearity is tested using a reduced code range: Codes 32 to 1023.
4 To achieve near zero output current, use the power-down feature.
5 Guaranteed by design and characterization; not production tested.
6 Input filtering on both the SCL and SDA inputs suppresses noise spikes that are less than 50 ns.
