LT1259/LT1260
T
he
G
denotes specifications which apply over the specified operating
temperature range.
Note 1:
A heat sink may be required depending on the power supply
voltage and how many amplifiers have their outputs short circuited.
Note 2:
Commercial grade parts are designed to operate over the
temperature range of –40
°
C to 85
°
C but are neither tested nor guaranteed
beyond 0

C to 70
°
C. Industrial grade parts specified and tested over
–40
°
C to 85
°
C are available on special request. Consult factory.
Note 3:
Ground pins are not internally connected. For best
performance, connect to ground.
Note 4:
T
J
is calculated from the ambient temperature T
A
and the
power dissipation P
D
according to the following formulas:
LT1259CN/LT1259IN: T

Note 5:
The supply current of the LT1259/LT1260 has a negative
temperature coefficient. See Typical Performance Characteristics.
Note 6:
Slew rate is measured at
±
5V on a
±
10V output signal while
operating on
±
15V supplies with R
F
= 1k, R
G
= 110
and R
L
= 1k.
Note 7:
Turn-on delay time is measured while operating on
±
5V
supplies with R
F
= 1k, R
G
= 110
and R
L
= 150
. The t
ON
is measured
from control input to appearance of 0.5V at the output, for V
IN
= 0.1V.
Likewise, turn-off delay time is measured from control input to
appearance of 0.5V on the output for V
IN
= 0.1V.
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
°
.
Six identical amplifier stages were cascaded giving an effective
resolution of 0.016% and 0.016
°
.
