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.
Note 9:
Slew rate is measured in A
V
= –1; input signal is
±
7.5V, output
measured at
±
2.5V.
Note 10:
This parameter is not 100% tested.

–40
