1 B grade: MCLK = 50 MHz; C grade: MCLK = 75 MHz. For specifications that do not specify a grade, the value applies to both grades.
2 Operating temperature range is as follows: B, C versions: −40°C to +105°C, typical specifications are at 25°C.
3 For compliance, with specified load of 200 Ω, IOUT 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.
