GENERAL DESCRIPTION
The AD8051 (single), AD8052 (dual), and AD8054 (quad) are
low cost, high speed, voltage feedback amplifiers. The amplifiers
operate on +3 V, +5 V, or 5 V supplies at low supply current.
They have true single-supply capability with an input voltage
range extending 200 mV below the negative rail and within 1 V
of the positive rail.
The AD8051/AD8052/AD8054 are well suited for video
electronics, cameras, video switchers, or any high speed portable
equipment. Low distortion and fast settling make them ideal for
active filter applications.
The AD8051/AD8052 in the 8-lead SOIC, the AD8052 in the
MSOP, the AD8054 in the 14-lead SOIC, and the 14-lead TSSOP
packages are available in the extended temperature range of
−40°C to +125°C.
Despite their low cost, the AD8051/AD8052/AD8054 provide
excellent overall performance and versatility. The output voltage
swings to within 25 mV of each rail, providing maximum output
dynamic range with excellent overdrive recovery.

ABSOLUTE MAXIMUM RATINGS
Table 4.
MAXIMUM POWER DISSIPATION
Parameter
Ratings
The maximum power that can be safely dissipated by the
AD8051/AD8052/AD8054 is limited by the associated rise in
junction temperature. The maximum safe junction temperature
for plastic encapsulated devices is determined by the glass
transition temperature of the plastic, approximately 150°C.
Temporarily exceeding this limit can cause a shift in parametric
performance due to a change in the stresses exerted on the die
by the package. Exceeding a junction temperature of 175°C for
an extended period can result in device failure.

While the AD8051/AD8052/AD8054 are internally short-
circuit protected, this cannot be sufficient to guarantee that the
maximum junction temperature (150°C) is not exceeded under
all conditions. To ensure proper operation, it is necessary to
observe the maximum power derating curves.

AD8051/AD8052/AD8054
THEORY OF OPERATION
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 do not cause phase reversal; however, the input
ESD devices 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.
CIRCUIT DESCRIPTION
The AD8051/AD8052/AD8054 are fabricated on the Analog
Devices, Inc. proprietary eXtra-Fast Complementary Bipolar
(XFCB) process, which enables the construction of PNP and
NPN transistors with similar fTs in the 2 GHz to 4 GHz region.
The process is dielectrically isolated to eliminate the parasitic
and latch-up 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 40). The smaller signal swings required on the first stage
outputs (nodes SIP, SIN) reduce the effect of nonlinear currents
due to junction capacitances and improve the distortion per-
formance. This design achieves harmonic distortion of −80 dBc
@ 1 MHz into 100 Ω with VOUT = 2 V p-p (gain = +1) on a
single 5 V supply.
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 allows the AD8054 to drive
30 mA of output current with the outputs within 0.5 V of the
supply rails.

APPLICATION INFORMATION
OVERDRIVE RECOVERY
V
= 5V
S
Overdrive of an amplifier occurs when the output and/or input
range is exceeded. The amplifier must recover from this over-
drive condition. As shown in Figure 41, the AD8051/AD8052/
AD8054 recover 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. Figure 42
and Figure 43 show their 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 value resistor in series with the load. Figure 44
and Figure 45 show the effect of a series resistor on the capaci-
tive 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 is
dominated by the roll-off of the series resistor and the load
capacitance.

LAYOUT CONSIDERATIONS
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.
Note that the unused amplifier’s inputs should be tied to ground.

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 parasitic capacitance.

Chip capacitors should be used for 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 to keep the parasitic capacitance at this node 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 affect active filter
performance.

ANALOG-TO-DIGITAL AND DIGITAL-TO-ANALOG
APPLICATIONS
Figure 50 is a schematic showing the AD8051 used as a driver
for an AD9201, a 10-bit, 20 MSPS, dual analog-to-digital
converter. This converter is designed to convert I and Q signals in
communications systems. In this application, only the I channel
is being driven. The I channel is enabled by applying a logic
high to SELECT (Pin 13).

The AD8051 is running from a dual supply and is configured
for a gain of +2. The input signal is terminated in 50 Ω and the
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 ADC.

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 22), 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 16) 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 swings both positive
and negative with respect to the bias voltage applied to INB-I.

dynamic swing requirements are a signal that is mostly low but
goes high with a duty cycle that is a small fraction of a percent,
and the other extreme defined by the opposite condition.
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, such as analog-to-
digital conversion, it is not desirable to have the sync pulses on
the video signal. These pulses 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 have negative-going
excursions in 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 removes the synchronizing pulses from a video
signal while passing all the useful video information. Figure 51
shows a practical single-supply circuit that uses only a single
AD8051. It is capable of directly driving a reverse terminated
video line.
VIDEO WITHOUT SYNC
VIDEO WITH SYNC
As a result of the duty cycles between the two extremes
previously presented, a 1 V p-p composite video signal that is
multiplied by a gain of 2 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 arbitrarily varying duty cycle without distortion.

Some circuits use a sync tip clamp to hold the sync tips at a
relatively constant level to lower the amount of dynamic signal
swing required. However, these circuits can have artifacts, such
as 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 52 is a standard composite
(1 V p-p) video signal that has the blanking level at ground. The

supply voltage.

Figure 51. Sync Stripper
The video signal plus sync is applied to the noninverting input
with the proper termination. The amplifier gain is set to 2 via
the two 1 kꢀ resistors in the feedback circuit. A bias voltage
must be applied to R1 so that the input signal has the sync
pulses stripped at the proper level.
The feedback circuit provides unity gain for the dc-biasing of
the input and provides a gain of 2 for any signals that are in the
video bandwidth. The output is ac-coupled and terminated to
drive the line.
The blanking level of the input video pulse is the desired place to
remove the sync information. This level is multiplied by 2 by the
amplifier. This level must be at ground at the output 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.
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.
SINGLE-SUPPLY COMPOSITE VIDEO LINE DRIVER
5V
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
can arise from such techniques.
