LT1881/LT1882

6

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

of a device may be impaired.

Note 2: The inputs are protected by internal resistors and back-to-back

diodes. If the differential input voltage exceeds

±0.7V, the input current

should be limited externally to less than 10mA.

Note 3: A heat sink may be required to keep the junction temperature

below absolute maximum.

Note 4: The LT1881C, LT1882C, LT1881I and LT1882I are guaranteed

functional over the operating temperature range of – 40

°C to 85°C.

Note 5: The LT1881C and LT1882C 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 LT1881I and LT1882I are

guaranteed to meet specified performance from – 40

°C to 85°C.

Note 6: This parameter is not 100% tested.

Note 7: Matching parameters are the difference between amplifiers

A and B in the LT1881; and between amplifiers A and D and B and C in the

LT1882.

Note 8: This parameter is the difference between the two noninverting

input bias currents.

Note 9:

∆CMRR and ∆PSRR are defined as follows: CMRR and PSRR are

measured in

µV/V on each amplifier. The difference is calculated in µV/V

and then converted to dB.
