ELECTRICAL CHARACTERISTICS The ● denotes the specifications which apply over the full operating
temperature range, otherwise specifications are at TA = 25°C. VS = ±15V, VCM = VO = 0V unless otherwise noted.

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: 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 LT1677I 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
specified performance from – 40°C to 85°C.
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 at ±15V supplies.
Note 9: Slew rate is measured in AV = – 1; input signal is ±7.5V, output
measured at ±2.5V.
Note 10: This parameter is not 100% tested. VS = 3V and 5V limits are
guaranteed by correlation to VS = ±15V test.
Note 11: VS = 5V limits are guaranteed by correlation to VS = 3V and
VS = ±15V tests.
Note 12: VS = 3V limits are guaranteed by correlation to VS = 5V and
VS = ±15V tests.
Note 13: Guaranteed by correlation to slew rate at VS = ±15V and GBW at
VS = 3V and VS = ±15V tests.
