■
The LT®1194 is a video difference amplifier optimized for
operation on ±5V and a single 5V supply. The amplifier has
a fixed gain of 20dB and features adjustable input limiting
to control tough overdrive applications. It has uncommitted high input impedance (+) and (–) inputs, and can be

Note 5: Slew rate is measured between ±1V on the output, with a ±0.3V
input step.
Note 6: Full-power bandwidth is calculated from the slew rate
measurement:
FPBW = SR/2πVP.
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).
Note 9: AC parameters are 100% tested on the ceramic and plastic DIP
packaged parts (J and N suffix) and are sample tested on every lot of the
SO packaged part (S suffix).
Note 1: Absolute Maximum Ratings are those values beyond which the
life of a device may be impaired.
Note 2: A heat sink is required to keep the junction temperature below
absolute maximum when the output is shorted.
Note 3: There are two limitations on signal swing. Output swing is limited
by clipping or saturation in the output stage. Input swing is controlled by
an adjustable input limiting function. On VS = ±5V, the overload
characteristic is output limiting, but on ±8V the overload characteristic is
input limiting. VOMAX is measured with the null pins open circuit.
Note 4: Output amplitude is reduced by the input limiting function. The
input limiting function occurs when the null pins, 1 and 8, are tied together
and raised to a potential 0.3V or more above the negative supply.

APPLICATIO S I FOR ATIO
The LT1194 is a video difference amplifier with a fixed gain
of 10 (20dB). The amplifier has two uncommitted high
input impedance (+) and (–) inputs that can be used either
differentially or single-ended. The LT1194 includes a
limiting feature that allows the amplifier to reduce its
output as a function of DC voltage on the BAL/VC pins. The
limiting feature uses input differential-pair limiting to
prevent overload in subsequent stages. This technique
allows extremely fast limiting action.

Power Supply Bypassing
The LT1194 is quite tolerant of power supply bypassing.
In some applications a 0.1µF ceramic disc capacitor
placed 1/2 inch from the amplifier is all that is required.

APPLICATIO S I FOR ATIO
A scope photo of the amplifier output with no supply
bypassing is used to demonstrate this bypassing tolerance, RL = 1k.
In many applications, and those requiring good settling
time, it is important to use multiple bypass capacitors. A
0.1µF ceramic disc in parallel with a 4.7µF tantalum is
recommended. Two oscilloscope photos with different
bypass conditions are used to illustrate the settling time
characteristics of the amplifier. Note that although the
output waveform looks acceptable at 1V/DIV, when amplified to 10mV/DIV the settling time to 10mV is 200ns. The
time drops to 162ns with multiple bypass capacitors, and
does not exhibit the characteristic power supply ringing.

Cable Terminations
The LT1194 video difference amplifier has been optimized
as a low cost cable driver. The ±50mA guaranteed output
current enables the LT1194 to easily deliver 7.5VP-P into
100Ω, while operating on ±5V supplies, or 2.6VP-P on a
single 5V supply.

IN DEMO BOARD, RL = 1k
Settling Time Poor Bypass
When driving a cable it is important to terminate the cable
to avoid unwanted reflections. This can be done in one of
two ways: single termination or double termination. With
single termination, the cable must be terminated at the
receiving end (75Ω to ground) to absorb unwanted energy. The best performance can be obtained by double
termination (75Ω in series with the output of the amplifier,
and 75Ω to ground at the other end of the cable). This
termination is preferred because reflected energy is absorbed at each end of the cable. When using the double
termination technique it is important to note that the signal
is attenuated by a factor of 2, or 6dB. For a cable driver with
a gain of 5 (LT1194 gain of 10), the –3dB bandwidth is over
30MHz with no peaking.

will appear at the (–) input if the feedback loop is properly
closed. In steady state the input signal appears at the
output of the LT1194, and 1/10 of this signal is applied
across the sense resistor. Thus the output current is
simply:
CC = 3pF
CC = 20pF

The compensation capacitor CC forces the LT1191 to be
the dominate pole for the loop, while the LT1194 is fast
enough to be transparent in the feedback path. The ratio of
the load resistor to the sense resistor should be approximately 10:1 or greater for easy compensation. For the
example shown the load resistor is 100Ω, the sense
resistor is 5.1Ω, and various loop compensation capacitors cause the output to exhibit an underdamped, critically
and overdamped response.

Other precautions include:
There are several precautions the user should take when
using the LT1194 in order to realize its full capability.
Although the LT1194 can drive a 50pF capacitive load,
isolating the capacitance with 10Ω can be helpful. Precautions primarily have to do with driving large capacitive
loads.
1. Use a ground plane (see Design Note 50, High Frequency Amplifier Evaluation Board).
2. Do not use high source impedances. The input capacitance of 2pF, and RS = 10k, for instance, will give an
8MHz – 3dB bandwidth.
3. PC board socket may reduce stability.
