Low Cost, +2.7V to 5.5V, 260MHz
Rail-to-Rail Amplifiers
FEATURES
ꢀ■
General Description
260MHz bandwidth
ꢀ■
Fully specified at +2.7V and +5V supplies
Output voltage range:
The CLC1005 (single), CLC1015 (single with disable), and CLC2005 (dual)
are low cost, voltage feedback amplifiers. These amplifiers are designed
to operate on +2.7V to +5V, or 2.5V supplies. The input voltage range
extends 300mV below the negative rail and 1.2V below the positive rail.
ꢀ■
ꢀ■
❏■
0.036V to 4.953V; VS = +5; RL = 2kΩ
Input voltage range:
❏■
-0.3V to +3.8V; VS = +5
TheCLC1005,CLC1015,andCLC2005offer superiordynamicperformance
with 260MHz small signal bandwidth and 145V/μs slew rate.The amplifiers
consume only 4.2mA of supply current per channel and the CLC1015 offers
a disable supply current of only 127μA.The combination of low power, high
output current drive, and rail-to-rail performance make these amplifiers well
suited for battery-powered communication/computing systems.

145V/μs slew rate
4.2mA supply current
Power down to 127μA
55mA linear output current
85mA short circuit current
CLC2005 directly replaces AD8052/42/92
in single supply applications
CLC1005 directly replaces AD8051/41/91
in single supply applications
The combination of low cost and high performance make the CLC1005,
CLC1015, and CLC2005 suitable for high volume applications in both
consumer and industrial applications such as interactive whiteboards,
wireless phones, scanners, color copiers, and video transmission.

General Description
The CLC1005, CLC1015, and CLC2005 are single supply,
general purpose, voltage-feedback amplifiers fabricated
on a complementary bipolar process using a patented
topography. They feature a rail-to-rail output stage and are
unity gain stable. Both gain bandwidth and slew rate are
insensitive to temperature.

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.

Figures 1, 2, and 3 illustrate typical circuit configurations for

At non-inverting gains other than G = +1, keep R below 1kΩ
g
to minimize peaking; thus for optimum response at a gain of
+2, a feedback resistor of 1kΩ is recommended. Figure 5
illustrates the CLC1005, CLC1015 and CLC2005 frequency
response with both 1kΩ and 2kΩ feedback resistors.

supplies.
Overdrive Recovery
For an amplifier, 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 CLC1005,
CLC1015, and CLC2005 will typically recover in less than
20ns from an overdrive condition. Figure 6 shows the
CLC2005 in an overdriven condition.

Enable/Disable Function
The CLC1015 offers an active-low disable pin that can be
used to lower its supply current. Leave the pin floating to
enable to part. Pull the disable pin to the negative supply
(which is ground in a single supply application) to disable
the output. During the disable condition, the nominal supply
current will drop below 127μA and the output will be at a
high impedance with about 2pF capacitance.

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.
Assuming the load is referenced in the middle of the power
rails or V /2.

The CLC1015 is short circuit protected. However, this may
not guarantee that the maximum junction temperature
(+150°C) is not exceeded under all conditions. Figure 7
shows the maximum safe power dissipation in the package
vs. the ambient temperature for the packages available.
Maximum power levels are set by the absolute maximum
junction rating of 150°C. To calculate the junction

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:

Driving Capacitive Loads
Evaluation Board Information
Increased phase delay at the output due to capacitive loading
can cause ringing, peaking in the frequency response, and
The following evaluation boards are available to aid in the
testing and layout of these devices:
possible unstable behavior. Use a series resistance, R ,
S
between the amplifier and the load to help improve stability
and settling performance. Refer to Figure 8.

For a given load capacitance, adjust R to optimize the

tradeoff between settling time and bandwidth. In general,
reducing R will increase bandwidth at the expense of
S
additional overshoot and ringing.
