Temperature range is as follows: B Version = −30°C to +85°C.

Linearity is tested using a reduced code range: Code 32 to Code 1023.
To achieve near zero output current, use the power-down feature.
Guaranteed by design and characterization; not production tested. XSHUTDOWN is active low. SDA and SCL pull-up resistors are tied to 1.8 V.
Input filtering on both the SCL and the SDA inputs suppresses noise spikes that are less than 50 ns.
XSHUTDOWN is active low.
