B grade: MCLK = 50 MHz; C grade: MCLK = 75 MHz. For specifications that do not specify a grade, the value applies to both grades.
Operating temperature range is as follows: B, C versions: −40°C to +105°C, typical specifications are at 25°C.

For compliance, with specified load of 200 Ω, I
OUT
full scale should not exceed 4 mA.
4
Guaranteed by design.
5
Applies when REFOUT is sourcing current. The impedance is higher when REFOUT is sinking current.
6
Measured with the digital inputs static and equal to 0 V or DVDD.
