General Description
APPLICATIONS
n Active Filters
n Audio Amplifiers
n Audio AC-3 Decoder Systems
n General purpose dual ampliifer
Typical Application - 2nd Order Low-Pass Audio Filter
The COMLINEAR CLC2058 is a dual voltage feedback amplifier that is internally frequency compensated to provide unity gain stability. The CLC2058
offers 3.5MHz of bandwidth at a gain of 2. The CLC2058 also features high
gain, low input voltage noise, high input resistance, and superb channel separation making it well suited for audio filter applications in set-top-boxes, DVD
players, and televisions.
The COMLINEAR CLC2058 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, 2, and 3 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.

Basic Operation
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 CLC2058 will typically recover in less
than 30ns from an overdrive condition. Figure 6 shows the
CLC2058 in an overdriven condition.
Figure 4 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 amplifier and the load to help
improve stability and settling performance. Refer to Figure 5.
Figure 6. Overdrive Recovery
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,

• Minimize all trace lengths to reduce series inductances
