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 LT1398C/LT1399C/LT1399HVC are guaranteed to meet
specified performance from 0 C to 70 C and are designed, characterized
and expected to meet these extended temperature limits, but are not tested
or QA sampled at – 40 C and 85 C. The LT1399I is guaranteed to meet
specified performance from –40 C to 85 C.

and characterization.
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 .
Note 9: The LT1398C, LT1398I, LT1399C, LT1399I, LT1399HVC and
LT1399HVI are guaranteed functional over the operating temperature
range of –40 C to 85 C.
