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: A heat sink may be required when the output is shorted indefinitely.
Note 3: The LT1222C is guaranteed to meet specified performance from 0°C
to 70°C and is designed, characterized and expected to meet these extended
temperature limits, but is not tested at –40°C and 85°C. The LT1222I is
guaranteed to meet the extended temperature limits.
Note 4: Input offset voltage is pulse tested and is exclusive of warm-up drift.
Note 5: Slew rate is measured between ±10V on an output swing of ±12V.
Note 6: FPBW = SR/2πV
P
.
Note 7: Differential Gain and Phase are tested with five amps in series.
Attenuators of 1/Gain are used as loads.
