Programming voltage
VTRIP programmed voltage range
Initial VTRIP program voltage accuracy (VCC applied - VTRIP) (Programmed at 25°C.)
Subsequent VTRIP program voltage accuracy [(VCC applied - Vta1) - VTRIP.
Programmed at 25°C.)
Vtr
VTRIP program voltage repeatability (Successive program operations. Programmed
at 25°C.)
Vtv
VTRIP program variation after programming (0-75°C). (programmed at 25°C)
VTRIP programming parameters are periodically sampled and are not 100% tested.
