Comlinear CLC2059
®
Dual, Low Noise, 4V to 36V Amplifier
The COMLINEAR CLC2059 is a low noise, dual voltage feedback amplifier
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-amplifiers, 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 amplifier pin-out and is available in a Pb-free, RoHS compliant SOIC-8
package.

Application Information
Power Dissipation
Figures 1 and 2 illustrate typical circuit configurations 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.
Power dissipation should not be a factor when operating
under the stated 2k ohm 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.

Power delivered to a purely resistive load is:

Pload = ((VLOAD)RMS2)/Rloadeff
The effective load resistor (Rloadeff) will need to include

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 specified 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
PDYNAMIC = (VS+ - VLOAD)RMS × ( ILOAD)RMS
Assuming the load is referenced in the middle of the power rails or Vsupply/2.
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 CLC2059 will typically recover in less
than 5μs from an overdrive condition. Figure 6 shows the
CLC2059 in an overdriven condition.
Figure 4 shows the maximum safe power dissipation in
the package vs. the ambient temperature for the packages available.

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 parasitic capacitance
• Minimize all trace lengths to reduce series inductances
Refer to the evaluation board layouts below for more information.
