Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
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.
The
θ
JA
specified for the DD package is with minimal PCB heat spreading
metal. Using expanded metal area on all layers of a board reduces
this value.
Note 4:
The LT1395C/LT1396C/LT1397C are guaranteed functional over
the operating temperature range of – 40°C to 85°C. The LT1397H is
guaranteed functional over the operating temperature range of –40°C
to 125°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 are not tested or QA sampled at these temperatures.
The LT1397H is guaranteed to meet specified performance from –40°C to
125°C. For guaranteed I-grade parts, consult the factory.
Note 6:
T
J
is calculated from the ambient temperature T
A
and the
power dissipation P
D
according to the following formula:
LT1395CS5: T
J
= T
A

LT1397HDE: T

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°.
Note 9:
For LT1395CS6, turn-on delay time (t
ON
) is measured from
control input to appearance of 1V(50%) at the output, for V
IN
= 1V and
A
V
= 2. Likewise, turn-off delay time (t
OFF
) is measured from control
input to appearance of 1V(50%) on the output for V
IN
= 1V and
A
V
= 2. This specification is guaranteed by design and characterization.
