The LT
1195 is a video operational amplifier optimized for
operation on single 5V and 5V supplies. Unlike many
high speed amplifiers, the LT1195 features high open-
loop gain, over 75dB, and the ability to drive heavy loads
to a full power bandwidth of 8.5 MHz at 6V
P-P
.
The LT1195
has a unity-gain stable bandwidth of 50MHz, a 60 phase
margin and consumes only 12mA of supply current,
making it extremely easy to use.
Because the LT1195 is a true operational amplifier, it is an
ideal choice for wideband signal conditioning, fast
integrators, peak detectors, active filters, and applications
requiring speed, accuracy, and low cost.
The LT1195 is a low power version of the popular LT1190,
and is available in 8-pin miniDIPs and SO packages with
standard pinouts. The normally unused Pin 5 is used for a
shutdown feature that shuts off the output and reduces
power dissipation to a mere 15mW.

Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: A heat sink may be required to keep the junction temperature
below absolute maximum when the output is shorted continuously.
Note 3: T
J
is calculated from the ambient temperature T
A
and power
dissipation P
D
according to the following formats:
LT1195MJ8/LT1195CJ8:
T
J
= T
A
+ (P

100C/ W)
LT1195N:

J
= T

Note 4: Exceeding the input common mode range may cause the output
to invert.
Note 5: Slew rate is measured between 1V on the output, with 3V input
step.
Note 6: Full power bandwidth is calculated from the slew rate
measurement: FPBW = SR/2V
P.
Note 7: Settling time measurement techniques are shown in "Take the
Guesswork Out of Settling Time Measurements," EDN, September 19, 1985.
Note 8: NTSC (3.58MHz). For R
L
= 1k, Diff A
V
= 0.3%, Diff Ph = 0.35.
Note 9: See Applications Information section for shutdown at elevated
temperatures. Do not operate the shutdown above T
J
> 125C.
Note 10: AC parameters are 100% tested on the ceramic and plastic DIP
packaged parts (J8 and N8 suffix) and are sample tested on every lot of
the SO packaged parts (S8 suffix).
Note 11: Do not operate at A
V
< 2 for T
A
< 0C.
