GENERAL DESCRIPTION
The ADA4851-1 (single), ADA4851-2 (dual), and ADA4851-4
(quad) are low cost, high speed, voltage feedback rail-to-rail
output op amps. Despite their low price, these parts provide
excellent overall performance and versatility. The 130 MHz,
−3 dB bandwidth and high slew rate make these amplifiers well
suited for many general-purpose, high speed applications.
See the Automotive Products section for more details. The
ADA4851 family is designed to work over the extended
temperature range (−40°C to +125°C).

The ADA4851 family is designed to operate at supply voltages
as low as +3 V and up to 5 V. These parts provide true single-
supply capability, allowing input signals to extend 200 mV
below the negative rail and to within 2.2 V of the positive rail.
On the output, the amplifiers can swing within 60 mV of either
supply rail.

With their combination of low price, excellent differential gain
(0.08%), differential phase (0.09º), and 0.1 dB flatness out to
11 MHz, these amplifiers are ideal for consumer video applications.

RMS output voltages should be considered. If RL is referenced
to −VS, as in single-supply operation, the total drive power is
VS × IOUT. If the rms signal levels are indeterminate, consider the
worst case, when VOUT = VS/4 for RL to midsupply.

Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.
In single-supply operation with RL referenced to −VS, the worst
case is VOUT = VS/2.
Airflow increases heat dissipation, effectively reducing θJA.
In addition, more metal directly in contact with the package
leads and through holes under the device reduces θJA.
Figure 5 shows the maximum safe power dissipation in the
package vs. the ambient temperature for the 6-lead SOT-23
(170°C/W), the 8-lead MSOP (150°C/W), and the 14-lead
TSSOP (120°C/W) on a JEDEC standard 4-layer board. θJA
values are approximations.

θJA is specified for the worst-case conditions; that is, θJA is specified

Maximum Power Dissipation
The maximum safe power dissipation for the ADA4851-1/
ADA4851-2/ADA4851-4 is limited by the associated rise in
junction temperature (TJ) on the die. At approximately 150°C,
which is the glass transition temperature, the plastic changes its
properties. Even temporarily exceeding this temperature limit
may change the stresses that the package exerts on the die,
permanently shifting the parametric performance of the
amplifiers. Exceeding a junction temperature of 150°C for an
extended period can result in changes in silicon devices,
potentially causing degradation or loss of functionality.

The power dissipated in the package (PD) is the sum of the
quiescent power dissipation and the power dissipated in the die
due to the drive of the amplifier at the output. The quiescent
power is the voltage between the supply pins (VS) times the
quiescent current (IS).

The ADA4851-1/ADA4851-2/ADA4851-4 feature a high slew
rate input stage that is a true single-supply topology, capable of
sensing signals at or below the negative supply rail. The rail-to-
rail output stage can pull within 60 mV of either supply rail when
driving light loads and within 0.17 V when driving 150 Ω. High
speed performance is maintained at supply voltages as low as 2.7 V.
HEADROOM CONSIDERATIONS
These amplifiers are designed for use in low voltage systems.
To obtain optimum performance, it is useful to understand the
behavior of the amplifiers as input and output signals approach
the headroom limits of the amplifiers. The input common-mode
voltage range of the amplifiers extends from the negative supply
voltage (actually 200 mV below the negative supply), or from
ground for single-supply operation, to within 2.2 V of the positive
supply voltage. Therefore, at a gain of 3, the amplifiers can
provide full rail-to-rail output swing for supply voltages as low
as 3.3 V and down to 3 V for a gain of 4.

Exceeding the headroom limit is not a concern for any inverting
gain on any supply voltage as long as the reference voltage at the
positive input of the amplifier lies within the input common- mode
range of the amplifier.

The input stage is the headroom limit for signals approaching
the positive rail. Figure 40 shows a typical offset voltage vs. the
input common-mode voltage for the ADA4851-1/ADA4851-2/
ADA4851-4 amplifiers on a ±5 V supply. Accurate dc performance
is maintained from approximately 200 mV below the negative
supply to within 2.2 V of the positive supply. For high speed
signals, however, there are other considerations. Figure 41
shows −3 dB bandwidth vs. input common-mode voltage for a
unity-gain follower. As the common-mode voltage approaches
2 V of positive supply, the amplifier responds well but the
bandwidth begins to drop as the common-mode voltage
approaches the positive supply. This can manifest itself in
increased distortion or settling time. Higher frequency signals
require more headroom than the lower frequencies to maintain
distortion performance.

Figure 42 illustrates how the rising edge settling time for the
amplifier is configured as a unity-gain follower, stretching out
as the top of a 1 V step input that approaches and exceeds the
specified input common-mode voltage limit.
The amplifiers do not exhibit phase reversal, even for input
voltages beyond the voltage supply rails. Going more than 0.6 V
beyond the power supplies turns on protection diodes at the input
stage, which greatly increases the current draw of the devices.

For signals approaching the negative supply and inverting gain
and high positive gain configurations, the headroom limit is the
output stage. The ADA4851-1/ADA4851-2/ADA4851-4 amplifiers
use a common emitter output stage. This output stage maximizes
the available output range, limited by the saturation voltage of
the output transistors. The saturation voltage increases with the
drive current that the output transistor is required to supply due
to the collector resistance of the output transistor.

Output overload recovery is typically within 35 ns after the
input of the amplifier is brought to a nonoverloading value.
Figure 44 shows output recovery transients for the amplifier
configured in an inverting gain of 1 recovering from a saturated
output from the top and bottom supplies to a point at midsupply.

As the saturation point of the output stage is approached, the
output signal shows increasing amounts of compression and
clipping. As in the input headroom case, higher frequency
signals require slightly more headroom than the lower fre-
quency signals. Figure 16 illustrates this point by plotting the
typical harmonic distortion vs. the output amplitude.

The specified input common-mode voltage of the ADA4851-1/
ADA4851-2/ADA4851-4 is 200 mV below the negative supply
to within 2.2 V of the positive supply. Exceeding the top limit
results in lower bandwidth and increased rise time, as shown in
Figure 41 and Figure 42. Pushing the input voltage of a unity-
gain follower to less than 2 V from the positive supply leads to
the behavior shown in Figure 43—an increasing amount of output
error as well as a much increased settling time. The recovery time
from input voltages of 2.2 V or closer to the positive supply is
approximately 55 ns, which is limited by the settling artifacts
caused by transistors in the input stage coming out of saturation.

ADA4851-1/ADA4851-2/ADA4851-4
An example of an 8 MHz, three-pole, Sallen-Key, low-pass,
video reconstruction filter is shown in Figure 46. This circuit
features a gain of 3, has a 0.1 dB bandwidth of 8.2 MHz, and
over 17 dB attenuation at 27 MHz (see Figure 47). The filter has
three poles; two are active with a third passive pole (R6 and C4)
placed at the output. C3 improves the filter roll-off. R6, R7, and
R8 comprise the video load of 150 Ω. Components R6, C4, R7,
R8, and the input termination of the network analyzer form a
12.8 dB attenuator; therefore, the reference level is roughly
−3.3 dB, as shown in Figure 47.
SINGLE-SUPPLY VIDEO AMPLIFIER
The ADA4851 family of amplifiers is well suited for portable
video applications. When operating in low voltage single-supply
applications, the input signal is limited by the input stage
headroom. For additional information, see the Headroom
Considerations section. Table 6 shows the recommended values
for voltage, input signal, various gains, and output signal swing
for the typical video amplifier shown in Figure 45.

VIDEO RECONSTRUCTION FILTER
At higher frequencies, active filters require wider bandwidths to
work properly. Excessive phase shift introduced by lower frequency
op amps can significantly affect the filter performance.
A common application for active filters is at the output of video
DACs/encoders. The filter, or more appropriately, the video
reconstruction filter, is used at the output of a video DAC/
encoder to eliminate the multiple images that are created during
the sampling process within the DAC. For portable video appli-
cations, the ADA4851 family of amplifiers is an ideal choice due
to its lower power requirements and high performance.
