The AD8051/AD8052/AD8054 offer low power supply current and can operate on a single +3 V power supply. These
features are ideally suited for portable and battery powered
applications where size and power are critical.
The wide bandwidth and fast slew rate on a single +5 V supply
make these amplifiers useful in many general purpose, high speed
applications where dual power supplies of up to ±6 V and single
supplies from +3 V to +12 V are needed.
All of this low cost performance is offered in an 8-lead SOIC,
along with a tiny SOT-23-5 package (AD8051), a µSOIC
package (AD8052) and a TSSOP-14 (AD8054).

ideal for active filter applications.
PEAK-TO-PEAK OUTPUT VOLTAGE SWING
Despite their low cost, the AD8051/AD8052/AD8054 provide
excellent overall performance and versatility. The output voltage swing extends to within 25 mV of each rail, providing the
maximum output dynamic range with excellent overdrive recovery. This makes the AD8051/AD8052/AD8054 useful for video
electronics such as cameras, video switchers or any high speed

accumulate on the human body and test equipment and can discharge without detection.
Although the AD8051/AD8052/AD8054 feature proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper
ESD precautions are recommended to avoid performance degradation or loss of functionality.

Overdrive Recovery
Overdrive of an amplifier occurs when the output and/or input
range are exceeded. The amplifier must recover from this overdrive condition. As shown in Figure 36, the AD8051/AD8052/
AD8054 recovers within 60␣ ns from negative overdrive and
within 45␣ ns from positive overdrive.

Driving Capacitive Loads
Consider the AD8051/AD8052 in a closed-loop gain of +1 with
+VS = 5 V and a load of 2 kΩ in parallel with 50 pF. Figures 37
and 38 show its frequency and time domain responses, respectively, to a small-signal excitation. The capacitive load drive of
the AD8051/AD8052/AD8054 can be increased by adding a
low valued resistor in series with the load. Figures 39 and 40
show the effect of a series resistor on capacitive drive for varying
voltage gains. As the closed-loop gain is increased, the larger
phase margin allows for larger capacitive loads with less peaking. Adding a series resistor with lower closed-loop gains accomplishes the same effect. For large capacitive loads, the
frequency response of the amplifier will be dominated by the
roll-off of the series resistor and the load capacitance.

Circuit Description
The AD8051/AD8052/AD8054 is fabricated on Analog Devices’
proprietary eXtra-Fast Complementary Bipolar (XFCB) process, which enables the construction of PNP and NPN transistors with similar fTs in the 2 GHz–4 GHz region. The process is
dielectrically isolated to eliminate the parasitic and latch-up

REV. B
AD8051/AD8052/AD8054
problems caused by junction isolation. These features allow the
construction of high frequency, low distortion amplifiers with low
supply currents. This design uses a differential output input stage
to maximize bandwidth and headroom (see Figure 1). The smaller
signal swings required on the first stage outputs (nodes S1P, S1N)
reduce the effect of nonlinear currents due to junction capacitances
and improve the distortion performance. With this design harmonic distortion of –80 dBc @ 1 MHz into 100 Ω with VOUT =
2 V p-p (Gain = +1) on a single 5 V supply is achieved.
The inputs of the device can handle voltages from –0.2 V below
the negative rail to within 1 V of the positive rail. Exceeding
these values will not cause phase reversal; however, the input
ESD devices will begin to conduct if the input voltages exceed
the rails by greater than 0.5 V. During this overdrive condition,
the output stays at the rail.
The rail-to-rail output range of the AD8051/AD8052/AD8054
is provided by a complementary common-emitter output stage.
High output drive capability is provided by injecting all output stage predriver currents directly into the bases of the output
devices Q8 and Q36. Biasing of Q8 and Q36 is accomplished by
I8 and I5, along with a common-mode feedback loop (not
shown). This circuit topology allows the AD8051/AD8052 to drive
45 mA of output current and the AD8054 to drive 30 mA of output current with the outputs within 0.5␣ V of the supply rails.
to a minimum. Parasitic capacitance of less than 1 pF at the
inverting input can significantly affect high speed performance.
Stripline design techniques should be used for long signal traces
(greater than about 25 mm). These should be designed with a
characteristic impedance of 50 Ω or 75 Ω and be properly terminated at each end.
Active Filters
Active filters at higher frequencies require wider bandwidth op
amps to work effectively. Excessive phase shift produced by
lower frequency op amps can significantly impact active filter
performance.
Figure 42 shows an example of a 2␣ MHz biquad bandwidth
filter that uses three op amps of an AD8054. Such circuits are
sometimes used in medical ultrasound systems to lower the
noise bandwidth of the analog signal before A/D conversion.
Please note that the unused amplifiers’ inputs should be tied to
ground.

Layout Considerations
230
The specified high speed performance of the AD8051/AD8052/
AD8054 requires careful attention to board layout and component selection. Proper RF design techniques and low-parasitic
component selection are necessary.
240
10k
The PCB should have a ground plane covering all unused portions of the component side of the board to provide a low impedance path. The ground plane should be removed from the
area near the input pins to reduce the parasitic capacitance.
Chip capacitors should be used for the supply bypassing. One
end should be connected to the ground plane and the other
within 3 mm of each power pin. An additional large (4.7␣ µF to
10 µF) tantalum electrolytic capacitor should be connected in
parallel, but not necessarily so close, to supply current for fast,
large signal changes at the output.
The feedback resistor should be located close to the inverting
input pin in order to keep the parasitic capacitance at this node

Figure 44. AD8051 Driving an AD9201, a 10-Bit 20 MSPS A/D Converter
applied to the noninverting input of the AD8051. The amplifier
output is 2 V p-p, which is the maximum input range of the
AD9201. The 22 Ω series resistor limits the maximum current
that flows and helps to lower the distortion of the A/D.
The AD9201 has differential inputs for each channel. These are
designated the A and B inputs. The B inputs of each channel are
connected to VREF (Pin 8) which supplies a positive reference
of 2.5 V. Each of the B inputs has a small low pass filter that
also helps to reduce distortion.
The output of the op amp is ac coupled into INA-I (Pin 2) via
two parallel capacitors to provide good high frequency and low
frequency coupling. The 1 kΩ resistor references the signal to
VREF that is applied to INB-I. Thus, INA-I will swing both

With the sampling clock running at 20 MSPS, the A/D output
was analyzed with a digital analyzer. Two input frequencies
were used, 1 MHz and 9.5 MHz, which is just short of the
Nyquist frequency. These signals were well filtered to minimize
any harmonics.
Figure 45 shows the FFT response of the A/D for the case of
1 MHz analog input. The SFDR is 71.66 dB and the A/D is
producing 8.8 ENOB (effective number of bits). When the
analog frequency was raised to 9.5 MHz, the SFDR was reduced to 60.18 dB and the A/D operated with 8.46 ENOBs as
shown in Figure 46. The inclusion of the AD8051 in the circuit
had no worsening of the distortion performance of the AD9201.

goes high with a duty cycle that is a small fraction of a percent.
The opposite condition defines the other extreme.
Sync Stripper
Synchronizing pulses are sometimes carried on video signals so
as not to require a separate channel to carry the synchronizing
information. However, for some functions, like A/D conversion,
it is not desirable to have the sync pulses on the video signal.
These pulses will reduce the dynamic range of the video signal
and do not provide any useful information for such a function.
The worst case of composite video is not quite this demanding.
One bounding condition is a signal that is mostly black for an
entire frame, but has a white (full amplitude) minimum width
spike at least once in a frame.
The other extreme is for a full white video signal. The blanking
intervals and sync tips of such a signal will have negative-going
excursions is compliance with the composite video specifications. The combination of horizontal and vertical blanking intervals limit such a signal to being at the highest (white) level for a
maximum of about 75% of the time.
A sync stripper will remove the synchronizing pulses from a
video signal while passing all the useful video information. Figure 47 shows a practical single supply circuit that uses only a
single AD8051. It is capable of directly driving a reverse terminated video line.
VBLANK
As a result of the duty cycles between the two extremes presented above, a 1 V p-p composite video signal that is multiplied
by a gain of two requires about 3.2 V p-p of dynamic voltage
swing at the output for an op amp to pass a composite video
signal of arbitrary varying duty cycle without distortion.

GROUND
Some circuits use a sync tip clamp to hold the sync tips at a
relatively constant level in order to lower the amount of dynamic
signal swing required. However, these circuits can have artifacts
like sync tip compression unless they are driven by a source with
a very low output impedance. The AD8051/AD8052/AD8054
have adequate signal swing when running on a single +5 V
supply to handle an ac coupled composite video signal.

The input to the circuit in Figure 48 is a standard composite
(1 V p-p) video signal that has the blanking level at ground. The
input network level shifts the video signal by means of ac coupling. The noninverting input of the op amp is biased to half of
the supply voltage.

Figure 47. Sync Stripper
The feedback circuit provides unity gain for the dc biasing of the
input, and provides a gain of two for any signals that are in the
video bandwidth. The output is ac coupled and terminated to
drive the line.
The video signal plus sync is applied to the noninverting input
with the proper termination. The amplifier gain is set equal to
two via the two 1 kΩ resistors in the feedback circuit. A bias
voltage must be applied to R1 in order that the input signal has
the sync pulses stripped at the proper level.
The capacitor values were selected for providing minimum “tilt”
or field time distortion of the video signal. These values would
be required for video that is considered to be studio or broadcast quality. However, if a lower consumer grade of video,
sometimes referred to as “consumer video” is all that is desired,
the values and the cost of the capacitors can be reduced by as
much as a factor of five with minimum visible degradation in the
picture.
The blanking level of the input video pulse is the desired place
to remove the sync information. This level is multiplied by two
by the amplifier. This level must be at ground at the output in
order for the sync stripping action to take place. Since the gain
of the amplifier from the input of R1 to the output is –1, a voltage equal to 2 × VBLANK must be applied to make the blanking
level come out at ground.

Single Supply Composite Video Line Driver
Many composite video signals have their blanking level at
ground and have video information that is both positive and
negative. Such signals require dual supply amplifiers to pass
them. However, by ac level shifting a single supply amplifier can
be used to pass these signals. The following complications may
arise from such techniques.
Signals of bounded peak-to-peak amplitude that vary in duty
cycle require larger dynamic swing capacity than their (bounded)
peak to peak amplitude after they are ac coupled. As a worst
case, the dynamic signal swing will approach twice the peakto-peak value. The two conditions that define the maximum
dynamic wing requirements are a signal that is mostly low, but
