The LTC1195 is a video operational amplifier optimized for
operation on single 5V and
5V supply. 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, and 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 inte-
grators, 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: A heat sink may be required to keep the junction temperature
below absolute maximum when the output is shorted continuously.
Note 2: 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

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