The q denotes specifications which apply over the specified operating temperature range, otherwise specifications are at TA = 25°C.
For each amplifier: VCM = 0V, VS = ±7.5V, EN = 0V, pulse tested, unless otherwise noted. (Note 4)

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.
Note 5: TJ is calculated from the ambient temperature TA and the
power dissipation PD according to the following formula:
LT1398CS, LT1399CS, LT1399IS, LT1399HVCS:
TJ = TA + (PD 100°C/W)
LT1399CGN, LT1399IGN: TJ = TA + (PD 120°C/W)
Note 6: Slew rate is measured at
±2V on a ±3V output signal.
Note 7: Turn-on delay time (tON) is measured from control input to
appearance of 1V at the output, for VIN = 1V. Likewise, turn-off delay
time (tOFF) is measured from control input to appearance of 0.5V on
the output for VIN = 0.5V. This specification is guaranteed by design
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.
