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, IOUT 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.
