Note 1: Absolute Maximum Ratings are those values beyond which the life

of a device may be impaired.

Note 2: All versions of the LTC6943 are guaranteed functional over the

operating temperature range of –40°C to 125°C. The LTC6943CGN is

guaranteed to meet 0°C to 70°C specifications and is designed,

characterized and expected to meet the specified performance from –40°C

ELECTRICAL CHARACTERISTICS The ● denotes specifications which apply over the full operating temperature

range, otherwise specifications are at TA = 25°C. V+ = 10V, V– = 0V

to 85°C but it is not tested or QA sampled at these temperatures.

The LTC6943IGN is guaranteed to meet specified performance from –40°C

to 85°C. The LTC6943HGN is guaranteed to meet specified performance

from –40°C to 125°C.

Note 3: OFF leakage current at 25°C is guaranteed by design and it is not

100% tested in production.
