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.
