LTC6078/LTC6079

60789fa

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

below the absolute maximum. This depends on the power supply voltage

and how many ampliﬁers are shorted.

Note 3: The LTC6078C/LTC6079C and LTC6078I/LTC6079I are guaranteed

functional over the operating temperature range of –40°C to 85°C. The

LTC6078H/LTC6079H are guaranteed functional over the operating

temperature range of –40°C to 125°C.

Note 4: The LTC6078C/LTC6079C are guaranteed to meet speciﬁed

performance from 0°C to 70°C. The LTC6078C/LTC6079C are designed,

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

to 85°C but are not tested or QA sampled at these temperatures. The

LTC6078I/LTC6079I are guaranteed to meet speciﬁed performance from

–40°C to 85°C. The LTC6078H/LTC6079H are guaranteed to meet speciﬁed

performance from –40°C to 125°C.

Note 5: VOS and VOS drift are 100% tested at 25°C and 125°C.

Note 6: IB and IOS are guaranteed by the VS = 5V test.

Note 7: VOS drift is guaranteed by the VS = 3V test.

Note 8: Current noise is calculated from in = √2qIB, where q = 1.6 • 10

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

temperature range, otherwise speciﬁcations are at TA = 25°C. Test conditions are V

+ = 5V, V– = 0V, VCM = 0.5V unless otherwise noted.
