General Description
The XR8051 (single), XR8052 (dual) and XR8054 (quad) are low cost,
voltage feedback ampliers. These ampliers are designed to operate on
+3V to +5V, or ±5V supplies. The input voltage range extends 300mV below
the negative rail and 0.9V below the positive rail.
The XR8051, XR8052, and XR8054 offer superior dynamic performance
with a 260MHz small signal bandwidth and 190V/μs slew rate. The
combination of low power, high output current drive, and rail-to-rail
performance make these ampliers well suited for battery-powered systems
and video applications.
The combination of low cost and high performance make the XR8051,
XR8052, and XR8054 suitable for high volume applications in both
consumer and industrial applications such as video surveillance and
distribution systems, professional and IPC cameras, active lter circuits,
coaxial cable drivers, and electronic white boards.

Application Information
General Description
The XR8051, XR8052, and XR8054 are single supply,
general purpose, voltage-feedback ampliers fabricated on
a complementary bipolar process using a patent pending
topography. They feature a rail-to-rail output stage and is
unity gain stable.
The common mode input range extends to 300mV below
ground and to 0.9V below Vs. Exceeding these values will
not cause phase reversal. However, if the input voltage
exceeds the rails by more than 0.5V, the input ESD devices
will begin to conduct. The output will stay at the rail during
this overdrive condition.
The design is short circuit protected and offers “soft”
saturation protection that improves recovery time.
Figures 1, 2, and 3 illustrate typical circuit congurations for
non-inverting, inverting, and unity gain topologies for dual
supply applications. They show the recommended bypass
capacitor values and overall closed loop gain equations. Figure
4 shows the typical non-inverting gain circuit for single supply
applications.

Overdrive Recovery
For an amplier, an overdrive condition occurs when the
output and/or input ranges are exceeded. The recovery time
varies based on whether the input or output is overdriven
and by how much the ranges are exceeded. The XR8051,
XR8052, and XR8054 will typically recover in less than 20ns
from an overdrive condition. Figure 5 shows the XR8052 in
an overdriven condition.

Power Dissipation
Power dissipation should not be a factor when operating
under the stated 2kΩ load condition. However, applications
with low impedance, DC coupled loads should be analyzed
to ensure that maximum allowed junction temperature is
not exceeded. Guidelines listed below can be used to verify
that the particular application will not cause the device to
operate beyond it’s intended operating range.
Maximum power levels are set by the absolute maximum
junction rating of 170°C. To calculate the junction
temperature, the package thermal resistance value ThetaJA
(θJA) is used along with the total die power dissipation.
TJunction = TAmbient + (θJA × PD)
Where TAmbient is the temperature of the working
environment.
In order to determine PD, the power dissipated in the load
needs to be subtracted from the total power delivered by the
supplies.
PD = Psupply - Pload
Supply power is calculated by the standard power equation.
Psupply = Vsupply × IRMSsupply
Vsupply = VS+ - VS-
Power delivered to a purely resistive load is:
Pload = ((Vload)RMS2)/Rloadeff
The effective load resistor (Rloadeff) will need to include the
effect of the feedback network. For instance,
Rloadeff in Figure 3 would be calculated as:
RL || (Rf + Rg)
These measurements are basic and are relatively easy to
perform with standard lab equipment. For design purposes
however, prior knowledge of actual signal levels and load
impedance is needed to determine the dissipated power.
Here, PD can be found from
PD = PQuiescent + PDynamic - Pload
Quiescent power can be derived from the specied IS values
along with known supply voltage, Vsupply. Load power can
be calculated as above with the desired signal amplitudes
using:
(Vload)RMS = Vpeak / √2
( Iload)RMS = ( Vload)RMS / Rloadeff
The dynamic power is focused primarily within the output
stage driving the load. This value can be calculated as:
PDynamic = (VS+ - Vload)RMS × ( Iload)RMS
Assuming the load is referenced in the middle of the power
rails or Vsupply/2.
The XR8051 is short circuit protected. However, this may not
guarantee that the maximum junction temperature (+150°C)
is not exceeded under all conditions. Figure 6 shows the
maximum safe power dissipation in the package vs. the
ambient temperature for the packages available.

Driving Capacitive Loads
Increased phase delay at the output due to capacitive loading
can cause ringing, peaking in the frequency response, and
possible unstable behavior. Use a series resistance, RS,
between the amplier and the load to help improve stability
and settling performance. Refer to Figure 7.

Table 1 provides the recommended RS for various capacitive
loads. The recommended RS values result in approximately
<1dB peaking in the frequency response.

Rev 1B
XR8051, XR8052, XR8054
For a given load capacitance, adjust RS to optimize the
tradeoff between settling time and bandwidth. In general,
reducing RS will increase bandwidth at the expense of
additional overshoot and ringing.
Layout Considerations
General layout and supply bypassing play major roles in
high frequency performance. Exar has evaluation boards to
use as a guide for high frequency layout and as an aid in
device testing and characterization. Follow the steps below
as a basis for high frequency layout:
Include 6.8µF and 0.1µF ceramic capacitors for power supply
decoupling
Place the 6.8µF capacitor within 0.75 inches of the power pin
Place the 0.1µF capacitor within 0.1 inches of the power pin
Remove the ground plane under and around the part,
especially near the input and output pins to reduce parasitic
capacitance
Minimize all trace lengths to reduce series inductances
Refer to the evaluation board layouts below for more
information.
Evaluation Board Information
The following evaluation boards are available to aid in the
testing and layout of these devices:

directly connected to the ground plane.
