ELECTRICAL CHARACTERISTICS
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:
T
J
is calculated from the ambient temperature T
A
and the
power dissipation P
D
according to the following formula:
LT1398CS, LT1399CS, LT1399HVCS: T
J
= T
A
+ (P
D
• 100°C/W)
LT1399CGN: T
J
= T
A
+ (P
D
• 120°C/W)
Note 6:
Slew rate is measured at
±2V
on a
±3V
output signal.
Note 7:
Turn-on delay time (t
ON
) is measured from control input to
appearance of 1V at the output, for V
IN
= 1V. Likewise, turn-off delay
time (t
OFF
) is measured from control input to appearance of 0.5V on
the output for V
IN
= 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°.
