General Description
The COMLINEAR CLC1009 (single) and CLC2009 (dual) are ultra-low power,
low cost, voltage feedback ampliers. These ampliers use only 208μA 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 CLC1009 and CLC2009 offer high bipolar performance at a low CMOS
price. They offer superior dynamic performance with a 35MHz small signal
bandwidth and 27V/μs slew rate. The combination of lowpower, high
bandwidth, and rail-to-rail performance make the CLC1009 and CLC2009 well
suited for battery-powered communication/ computing systems.

Application Information
General Description
The CLC1009 family are a single supply, general purpose,
voltage-feedback ampliers fabricated on a complementary
bipolar process. The CLC1009 offers 35MHz unity gain
bandwidth, 27V/μs slew rate, and only 208μA supply current.
It features a rail-to-rail output stage and is unity gain stable.
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.
The design uses a Darlington output stage. The output
stage is short circuit protected and offers “soft” saturation
protection that improves recovery time.
Figures 1, 2, and 3 illustrate typical circuit congurations 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 applicaitons.

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 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
Supply power is calculated by the standard power
equation.
Psupply = Vsupply × IRMS supply
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 specied 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 CLC1009 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
resistance, RS, between the amplier and the load to
help improve stability and settling performance. Refer to
Figure 6.

Overdrive Recovery
An overdrive condition is dened as the point when either
one of the inputs or the output exceed their specied
voltage range. Overdrive recovery is the time needed for
the amplier 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 CLC1009 and CLC2009 will typically recover
in less than 20ns from an overdrive condition.
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
▪ 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:

Evaluation Board Schematics
Evaluation board schematics and layouts are shown in

supply operation. Follow these steps to use the board in a
single-supply application:
1. Short -Vs to ground.
