FUNCTION AND VALUES
Monitor Diode Current Range
Imd_rng Sets the Full-Scale Range of the Monitor Diode Current.
Nominal Temperature
T_nom is the Temperature with Respect to Which All Temperature Compensation Calculations are
Made. T_nom is Usually the Temperature at Which the LTC5100 and Laser Diode were Set Up In
Production.
The Scaling is 512K or 239 C Full Scale, Corresponding to 0.5 C/LSB
T_nom = (T + 273 C)/0.5 C, Where T is the Nominal Temperature in Degrees Celsius.
