Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: This parameter is guaranteed to meet specified performance
through design and characterization. It has not been tested.
Note 3: A heat sink may be required depending on the power supply
voltage and how many amplifiers have their outputs short circuited.
Note 4: The LT1395C/LT1396C/LT1397C are guaranteed functional over
the operating temperature range of – 40 C to 85 C.
Note 5: The LT1395C/LT1396C/LT1397C are guaranteed to meet specified
performance from 0 C to 70 C. The LT1395C/LT1396C/LT1397C are
designed, characterized and expected to meet specified performance from
– 40 C and 85 C but is not tested or QA sampled at these temperatures.
For guaranteed I-grade parts, consult the factory.

Note 7: Slew rate is measured at 2V on a 3V output signal.
Note 8: Differential gain and phase are measured using a Tektronix
TSG120YC/NTSC signal generator and a Tektronix 1780R Video
Measurement Set. The resolution of this equipment is 0.1% and 0.1 .
Ten identical amplifier stages were cascaded giving an effective
resolution of 0.01% and 0.01 .
