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 5: Matching parameters are the difference between the two amplifiers
A and D and between B and C of the LT6207; between the two amplifiers of
the LT6206.
Note 6: This parameter is not 100% tested.
Note 2: The inputs are protected by back-to-back diodes. If the differential
input voltage exceeds 1.4V, the input current should be limited to less than
10mA.
Note 3: A heat sink may be required to keep the junction temperature
below absolute maximum. This depends on the power supply voltage and
how many amplifiers are shorted.
Note 4: The LT6205C/LT6206C/LT6207C are guaranteed to meet specified
performance from 0°C to 70°C and are designed, characterized and
expected to meet specified performance from –40°C to 85°C but are not
tested or QA sampled at these temperatures. The LT6205I/LT6206I/LT6207I
are guaranteed to meet specified performance from –40°C to 85°C. The
LT6205H is guaranteed to meet specified performance from –40°C to 125°C.
Note 7: Output voltage swings are measured between the output and
power supply rails.
Note 8: Full power bandwidth is calculated from the slew rate
measurement: FPBW = SR/2πV
.
PEAK
Note 9: There are reverse biased ESD diodes on all inputs and outputs.
If these pins are forced beyond either supply, unlimited current will flow
through these diodes. If the current is transient in nature and limited to
less than 25mA, no damage to the device will occur.

APPLICATIONS INFORMATION
Amplifier Characteristics
negativesupplypin.Foroptimumperformanceallfeedback
components and bypass capacitors should be contained
in a 0.5 inch by 0.5 inch area. This helps ensure minimal
stray capacitances.
Figure 1 shows a simplified schematic of the LT6205/
LT6206/LT6207. The input stage consists of transistors
Q1 to Q8 and resistor R1. This topology allows for high
slew rates at low supply voltages. The input common
mode range extends from ground to typically 1.75V from

IN
throughthesediodesiftheinputdifferentialvoltageexceeds
1.4V. The input stage drives the degeneration resistors of
PNP and NPN current mirrors, Q9 to Q12, which convert
the differential signals into a single-ended output. The
complementary drive generator supplies current to the
output transistors that swing from rail-to-rail.
The LT6205/LT6206/LT6207 are optimized for wide band-
width video applications. They can drive a capacitive load
of 20pF in a unity-gain configuration. When driving a
larger capacitive load, a resistor of 10Ω to 50Ω should
be connected between the output and the capacitive load
to avoid ringing or oscillation. The feedback should still
be taken from the output pin so that the resistor will
isolate the capacitive load and ensure stability. The Typi-
cal Performance Characteristics curves show the output
overshoot when driving a capacitive load with different
series resistors.
ThecurrentgeneratedthroughR1,dividedbythecapacitor
CM, determines the slew rate. Note that this current, and
hence the slew rate, are proportional to the magnitude
of the input step. The input step equals the output step
divided by the closed loop gain. The highest slew rates
are therefore obtained in the lowest gain configurations.
The Typical Performance Characteristics curve of Slew
Rate vs Closed-Loop Gain shows the details.
Video Signal Characteristics
Composite video is the most commonly used signal in
broadcast grade products and includes luma (or lumi-
nance,theintensityinformation),chroma(thecolorimetry
information) and sync (vertical and horizontal raster tim-
ing) elements combined into a single signal, NTSC and
PAL being the common formats. Component video for
entertainment systems include separate signal(s) for the
luma and chroma (i.e., Y/C or YPbPr) with sync generally
applied to the luma channel (Y signal). In some instances,
nativeRGBsignals(separateintensityinformationforeach
primary color: red, green, blue) will have sync included as
well. All the signal types that include sync are electrically
similar from a voltage-swing standpoint, though various
timing and bandwidth relationships exist depending on
the applicable standard.
ESD
The LT6205/LT6206/LT6207 have reverse-biased ESD
protection diodes on all inputs and outputs as shown in
Figure 1. If these pins are forced beyond either supply
unlimited current will flow through these diodes. If the
current is transient, and limited to 25mA or less, no dam-
age to the device will occur.
Layout and Passive Components
With a gain bandwidth product of 100MHz and a slew rate
of 450V/μs the LT6205/LT6206/LT6207 require special
attention to board layout and supply bypassing. Use a
ground plane, short lead lengths and RF quality low ESR
supply bypass capacitors. The positive supply pin should
be bypassed with a small capacitor (typically 0.01μF to
0.1μF) within 0.25 inches of the pin. When driving heavy
loads, an additional 4.7μF electrolytic capacitor should be
used. When using split supplies, the same is true for the

ing full composite) are specified to have nominal 1V

carry timing information, and by being at a lower potential
than all the other information, represents blacker-than-

invisible on a CRT. The black level of the waveform is at
(or set up very slightly above) the upper limit of the sync
information. Waveform content above the black level is
intensity information, with peak brightness represented
at the maximum signal level. In the case of composite
video, the modulated color subcarrier is superimposed on
Clamped AC-Input Cable Driver
A popular method of further minimizing supply require-
ments with AC-coupling is to employ a simple clamping
scheme, as shown in Figure 2. In this circuit, the LT6205
operates from 3.3V by having the sync tips control the
charge on the coupling capacitor C1, thereby reducing
the black level input wander to ≈ 0.07V. The only minor
drawback to this circuit is the slight sync tip compression
(≈ 0.025V at input) due to the diode conduction current,
thoughthepicturecontentremainsfullfidelity. Thiscircuit
has nearly the design margin of its DC-coupled counter-

only pass through one active stage from any input to any
output, with passive additions being performed by the
cableback-terminationresistors.Thecompromiseinusing
passive output addition is that the amplifier outputs must
be twice as large as that of a conventional cable driver. The
Y-channelsectionalsohasthedemandingrequirementthat
itsingle-handedlydrivesallthreeoutputstofullbrightness
during times of white content, so a helper current source
is used to assure unclipped video when operating from
5V supplies. This circuit maps sync-on-Y to sync on all
the RGB channels, and for best results should have input
black levels at 0V nominal to prevent clipping.
configuration forms a 2:1 resistor divider in the cabling
that must be accounted for in the driver amplifier by
delivering 2V output into an effective 2 • Z load (e.g.,
P-P
0
150Ω). Driving the cable can require more than 13mA
while the output is approaching the saturation limits of the
amplifier output. The absolute minimum supply is: V
=
MIN
2 + V +V . For example, the LT6206 dual operating on
OH
OL
3.3V as shown on the front page of this data sheet, with
exceptionally low V ≤ 0.5V and V ≤ 0.35V, provides a
OH
OL
design margin of 0.45V. The design margin must be large
enough to include supply variations and DC bias accuracy
for the DC-coupled video input.
Handling AC-Coupled Video Signals
AC-coupled video inputs are intrinsically more difficult to
handle than those with DC-coupling because the average
signal voltage of the video waveform is effected by the
picturecontent,meaningthattheblacklevelattheamplifier
wanders with scene brightness. The wander is measured
as 0.56V for a 1V NTSC waveform changing from black
P-P
field to white field and vice-versa, so an additional 1.12V
allowance must be made in the amplifier supply (assum-
ing gain of 2, so V
= 3.12 + V +V ). For example,
MIN
OH OL
an LT6205 operating on 5V has a conservative design
margin of 1.03V. The amplifier output (for gain of 2) must
swing +1.47V to –1.65V around the DC-operating point,
so the biasing circuitry needs to be designed accordingly
for optimal fidelity.
