General Description
The COMLINEAR CLC2059 is a low noise, dual voltage feedback amplier
that is internally frequency compensated to provide unity gain stability. The
CLC2059 offers 13.7MHz of unity gain bandwidth and excellent (110dB)
CMRR, PSRR, and open loop gain. The CLC2059 also features low input
voltage noise (0.7μVRMS) and low distortion (0.0005%) making it well suited
for audio applications to improve tone control. Other applications include
industrial measurement tools, pre-ampliers, and other circuits that require
well-matched channels.
The COMLINEAR CLC2059 is designed to operate over a wide power supply
voltage range, ±2V to ±18V (4V to 36V). It utilizes an industry standard
dual amplier pin-out and is available in a Pb-free, RoHS compliant SOIC-8
package.

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 purpos-
es 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 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.
Figure 4 shows the maximum safe power dissipation in
the package vs. the ambient temperature for the pack-
ages available.

Driving Capacitive Loads
Increased phase delay at the output due to capacitive
loading can cause ringing, peaking in the frequency re-
sponse, and possible unstable behavior. Use a series resis-
tance, RS, between the amplier and the load to help im-
prove stability and settling performance. Refer to Figure 5.

Overdrive Recovery
An overdrive condition is dened as the point when ei-
ther one of the inputs or the output exceed their specied
voltage range. Overdrive recovery is the time needed for
the amplier 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 CLC2059 will typically recover in less
than 5μs from an overdrive condition. Figure 6 shows the
CLC2059 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.
