ELECTRICAL CHARACTERISTICS The l denotes the speciﬁcations which apply over the full speciﬁed

temperature range, otherwise speciﬁcations are at TA = 25°C or as noted. V+ = 2.7V to 5.5V, RL = 15k, CL = 5pF, Pin 4 = V+ unless

otherwise noted. All voltages are with respect to GND.

Note 1: Stresses beyond those listed under Absolute Maximum Ratings

may cause permanent damage to the device. Exposure to any Absolute

Maximum Rating condition for extended periods may affect device

reliability and lifetime.

Note 2: Frequency accuracy is deﬁned as the deviation from the fOSC

equation. Accuracy is tested with DIV = V+, N = 1 and other divide ratios

are guaranteed by design.

Note 3: Jitter is the ratio of the peak-to-peak distribution of the period to

the mean of the period. This speciﬁcation is based on characterization and

is not 100% tested.

Note 4: To conform with the Logic IC Standard convention, current out of

a pin is arbitrarily given as a negative value.

Note 5: Output rise and fall times are measured between the 10% and

90% power supply levels.

Note 6: A heat sink may be required to keep the junction temperature

below the absolute maximum when the output is shorted indeﬁnitely.

Note 7: The LTC6905C is guaranteed functional over the operating

temperature range.

Note 8: The LTC6905C is guaranteed to meet speciﬁed performance from

0°C to 70°C. The LTC6905C-XXX is designed, characterized and expected

to meet speciﬁed performance from –40°C to 85°C but is not tested or QA

sampled at these temperatures. The LTC6905I-XXX is guaranteed to meet

speciﬁed performance from –40°C to 85°C.

Note 9: The LTC6905 is optimized for the performance with a 3V power

supply voltage. Please consult LTC Marketing for parts optimized for 5V

operation.
