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

of the device may be impaired.

Note 2: The inputs are protected by back-to-back diodes. Current limiting

resistors are not used in order to achieve low noise. If differential input

voltage exceeds

±1.4V, the input current should be limited to 25mA. If the

common mode range exceeds either rail, the input current should be

limited to 10mA.

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

below absolute maximum.

Note 4: The LT1677C and LTC1677I are guaranteed functional over the

Operating Temperature Range of – 40

°C to 85°C.

Note 5: The LT1677C is guaranteed to meet specified performance from

0

°C to 70°C. The LT1677C 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 LT1677I is guaranteed to meet the

extended temperature limits.

Note 6: Typical parameters are defined as the 60% yield of parameter

distributions of individual amplifier; i.e., out of 100 LT1677s, typically 60

op amps will be better than the indicated specification.

Note 7: See the test circuit and frequency response curve for 0.1Hz to

10Hz tester in the Applications Information section of the LT1677 data

sheet.

Note 8: Noise is 100% tested.

±2.5V.

Note 10: This parameter is not 100% tested.
