1
Operating temperature range is −40°C to +125°C; typical specifications are at 25°C.
2
For compliance with the specified load of 200 Ω, I
OUT
full scale should not exceed 4 mA.
3
Guaranteed by design.
4
Applies when REFOUT is sourcing current. The impedance is higher when REFOUT is sinking current.
5
Measured with the digital inputs static and equal to 0 V or DVDD.
