ELECTRICAL CHARACTERISTICS

Note 2: Both V + pins (11, 20) must be connected together and both

ground pins (1, 10) must be connected together.

The q denotes specifications which apply over the full operating

temperature range.

Note 1: TJ is calculated from the ambient temperature TA and power

dissipation PD according to the following formulas:

LT1161CN, LT1161IN: TJ = TA + (PD × 70°C/W)

LT1161CS, LT1161IS: TJ = TA + (PD × 110°C/W)
