LT1112/LT1114

111214fb

Note 5: Offset voltage, supply current and power supply rejection ratio are

measured at the minimum supply voltage.

Note 6: Matching parameters are the difference between amplifiers A and

D and between B and C on the LT1114; between the two amplifiers on the

LT1112.

Note 7: This parameter is the difference between two noninverting input

bias currents.

Note 8:

∆CMRR and ∆PSRR are defined as follows: (1) CMRR and PSRR

are measured in

µV/V on the individual amplifiers. (2) The difference is

calculated between the matching sides in

µV/V. (3) The result is converted

to dB.

Note 9: This parameter is not 100% tested.

ELECTRICAL CHARACTERISTICS

Note 10: These parameters are not tested. More than 99% of the op amps

tested during product characterization have passed the maximum limits.

100% passed at 1kHz.

Note 11: The LT1112AC/LT1112C/LT1112S8/LT1112I and LT1114AC/

LT1114C/LT1114S/LT1114I are guaranteed functional over the

temperature range of –40

°C to 85°C.

Note 12: The LT1112AC/LT1112C/LT1112S8/LT1114AC/LT1114C/

LT1114S are guaranteed to meet specified performance from 0

°C to 70°C

and 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 LT1112I/LT1114I are guaranteed to meet

specified performance from –40

°C to 85°C.
