Note 3: All typicals are given for VCC = 5V and TA = 25°C.

Note 4: The LTC1487 is not tested and is not quality-assurance sampled at

–40

°C and at 85°C. These specifications are guaranteed by design,

correlation, and/or inference from 0

°C, 25°C and/or 70°C tests.

The q denotes specifications which apply over the full operating

temperature range.

Note 1: Absolute maximum ratings are those beyond which the safety of

the device cannot be guaranteed.

Note 2: All currents into device pins are positive; all currents out ot device

pins are negative. All voltages are referenced to device ground unless

otherwise specified.
