Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: Input Offset Voltage measurements are performed by automatic
test equipment approximately 0.5 sec. after application of power. In
addition, at T
approximately 55 C to account for the chip temperature rise when the
device is fully warmed up.
Note 3: Long Term Input Offset Voltage Stability refers to the average
trend line of Offset Voltage vs. Time over extended periods after the first
30 days of operation. Excluding the initial hour of operation, changes in
V
Note 4: This parameter is tested on a sample basis only.
Note 5: 10Hz noise voltage density is sample tested on every lot with the
exception of the S8 and S16 packages. Devices 100% tested at 10Hz are
available on request.
Note 6: Current noise is defined and measured with balanced source
resistors. The resultant voltage noise (after subtracting the resistor noise

obtain current noise. Maximum 10Hz current noise can be inferred from
100% testing at 1kHz.
Note 7: Gain-bandwidth product is not tested. It is guaranteed by design
and by inference from the slew rate measurement.
Note 8: This parameter is not 100% tested.
Note 9: 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 1.8V, the input current should be limited to 25mA.
Note 10: This parameter guaranteed by design, fully warmed up at T
70 C. It includes chip temperature increase due to supply and load
currents.
Note 11: The LT1028/LT1128 are designed, characterized and expected to
meet these extended temperature limits, but are not tested at –40 C and
85 C. Guaranteed I grade parts are available. Consult factory.
