General Description
FEATURES
n 70μA supply current
n 7.3MHz bandwidth
n Input voltage range with 5V supply:
-0.3V to 3.8V
n Output voltage range with 5V supply:
0.04V to 4.96V
n 9V/μs slew rate
n 29nV/√Hz input voltage noise
n 4mA linear output current
n Fully specified at 2.7V and 5V supplies
n Competes with low power CMOS amps
The COMLINEAR CLC1010 (single) and CLC2010 (dual) are ultra-low power,
low cost, voltage feedback amplifiers. These amplifiers use only 70μA of
supply current and are designed to operate from a supply range of 2.5V to
5.5V (±1.25 to ±2.75). The input voltage range extends 300mV below the
negative rail and 1.2V below the positive rail.
The CLC1010 and CLC2010 offer high bipolar performance at a low CMOS
price. They offer superior dynamic performance with a 7.3MHz small
signal bandwidth and 9V/μs slew rate. The combination of low power, high
bandwidth, and rail-to-rail performance make the CLC1010 and CLC2010 well
suited for battery-powered communication/computing systems.
APPLICATIONS

The design utilizes a patent pending topology that provides
increased slew rate performance. The common mode input
range extends to 300mV below ground and to 1.2V 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.

Data Sheet
Maximum power levels are set by the absolute maximum
junction rating of 150°C. To calculate the junction
temperature, the package thermal resistance value
ThetaJA (ӨJA) is used along with the total die power
dissipation.
TJunction = TAmbient + (ӨJA × 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
PDYNAMIC = (VS+ - VLOAD)RMS × ( ILOAD)RMS
Assuming the load is referenced in the middle of the
power rails or Vsupply/2.
The CLC1010 is short circuit protected. However, this may
not guarantee that the maximum junction temperature
(+150°C) is not exceeded under all conditions. Figure 5
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

help improve stability and settling performance. Refer to

These measurements are basic and are relatively easy to

however, prior knowledge of actual signal levels and load
impedance is needed to determine the dissipated power.

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.
The dynamic power is focused primarily within the output
stage driving the load. This value can be calculated as:

1. Short -Vs to ground.
An overdrive condition is defined as the point when either
one of the inputs or the output exceed their specified
voltage range. Overdrive recovery is the time needed for
the amplifier to return to its normal or linear operating
point. The recovery time varies, based on whether the
input or output is overdriven and by how much the range is
exceeded. The CLC1010 and CLC2010 will typically recover
in less than 60ns from an overdrive condition.
2. Use C3 and C4, if the -VS pin of the amplifier is not
directly connected to the ground plane.

Layout Considerations
General layout and supply bypassing play major roles in
high frequency performance. CADEKA 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
Figure 8. CEB002 & CEB003 Schematic
▪▪Minimize all trace lengths to reduce series inductances
Refer to the evaluation board layouts below for more
information.
