General Description
The COMLINEAR CLC1050 (single), CLC2050 (dual), and CLC4050 (quad)
are voltage feedback ampliers that are internally frequency compensated to
provide unity gain stability. At unity gain (G=1), these ampliers offer 550kHz
of bandwidth. They consume only 0.5mA of supply current over the entire
power supply operating range. The CLC1050, CLC2050, and CLC4050 are
specically designed to operate from single or dual supply voltages.
The COMLINEAR CLC1050, CLC2050, and CLC4050 offer a common mode
voltage range that includes ground and a wide output voltage swing. The
combination of low-power, high supply voltage range, and low supply current
make these ampliers well suited for many general purpose applications and
as alternatives to several industry standard ampliers on the market today.
Typical Application - Voltage Controlled Oscillator (VCO)

Power Dissipation
Power dissipation should not be a factor when operating
under the stated 2k ohm load condition. However, ap-
plications 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 operat-
ing range.
Maximum power levels are set by the absolute maximum
junction rating of 150°C. To calculate the junction tem-
perature, 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 equa-
tion.
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 gure 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 val-
ues along with known supply voltage, VSupply. Load power
can be calculated as above with the desired signal ampli-
tudes 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 pow-
er rails or Vsupply/2.

ages available.

Driving Capacitive Loads
Increased phase delay at the output due to capacitive load-
ing 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 5.

Figure 5. Addition of RS for Driving
Capacitive Loads
Table 1 provides the recommended RS for various capaci-
tive loads. The recommended RS values result in <=1dB
peaking in the frequency response. The Frequency Re-
sponse vs. CL plot, on page 6, illustrates the response of
the CLCx050.

5nF 0 390
10nF 0 260
100 0 440
Table 1: Recommended RS vs. CL
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 ad-
ditional overshoot and ringing.
Overdrive Recovery
An overdrive condition is dened as the point when ei-
ther 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 CLCx050 will typically recover in less
than 30ns from an overdrive condition. Figure 6 shows the
CLC1050 in an overdriven condition.

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 para-
sitic capacitance
• Minimize all trace lengths to reduce series inductances
Refer to the evaluation board layouts below for more in-
formation.
Evaluation Board Information
The following evaluation boards are available to aid in the
testing and layout of these devices:
Evaluation Board # Products
CEB002 CLC1050
CEB006 CLC2050
CEB018 CLC4050
Evaluation Board Schematics
Evaluation board schematics and layouts are shown in Fig-
ures 7-14. These evaluation boards are built for dual- sup-
ply operation. Follow these steps to use the board in a
single-supply application:
1. Short -Vs to ground.
2. Use C3 and C4, if the -VS pin of the amplier is not
directly connected to the ground plane.
