LT1398/LT1399/LT1399HV
ELECTRICAL CHARACTERISTICS (LT1399HV)
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 LT1398/LT1399/LT1399HV 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 at
– 40°C and 85°C. Guaranteed I grade parts are available, consult factory.
Note 5: TJ is calculated from the ambient temperature TA and the
power dissipation PD according to the following formula:
LT1398CS, LT1399CS, LT1399HVCS: TJ = TA + (PD • 100°C/W)
LT1399CGN: 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°.
