(2) Parts are tested at 85 °C and specified by design and correlation over the full temperature range. (3) Typical values are at V+ = 3 V, TA = 25°C. (4) ∆r on = ron(max) – ron(min) (5) Flatness is defined as the difference between the maximum and minimum value of ron as measured over the specified analog signal ranges. (6) Leakage parameters are 100% tested at the maximum-rated hot operating temperature and specified by correlation at TA = 25°C. (7) OFF isolation = 20log10 (VCOM/VNO), VCOM = output, VNO = input to OFF switch 3 Submit Documentation Feedback |
