The Comlinear CLC2005 is a dual, low cost, voltage feedback amplifier.
This amplifier is designed to operate on +2.7V,+5V, or ±2.5V supplies. The
input voltage range extends 300mV below the negative rail and 1.2V below
the positive rail. The CLC2005 offers superior dynamic performance
with a 260MHz small signal bandwidth and 145V/μs slew rate. The
combination of low power, high output current drive, and rail-to-rail
performance make the Comlinear CLC2005 well suited for battery-powered communication/computing systems. The combination of low cost and
high performance make the Comlinear CLC2005 suitable for high volume
applications in both consumer and industrial applications such as wireless
phones, scanners, and color copiers.

Figure 1: Typical Configuration
At non-inverting gains other than G = +1, keep Rg below
1kΩ to minimize peaking; thus, for optimum response at a
gain of +2, a feedback resistor of 1kΩ is recommended.
Figure 2 illustrates the CLC2005 frequency response with
both 1kΩ and 2kΩ feedback resistors.

Power Dissipation
The maximum internal power dissipation allowed is directly
related to the maximum junction temperature. If the
maximum junction temperature exceeds 150°C, some
reliability degradation will occur. If the maximum junction
temperature exceeds 175°C for an extended time, device
failure may occur.
The CLC2005 is short circuit protected. However, this may
not guarantee that the maximum junction temperature
(+150°C) is not exceeded under all conditions. Follow the
maximum power derating curves shown in Figure 3 to
ensure proper operation.
Maximum Power Dissipation (W)
The design uses a Darlington output stage. The output
stage is short circuit protected and offers “soft” saturation
protection that improves recovery time.
Rf = 1kΩ
®
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.

Overdrive Recovery

Rev 1B
For an amplifier, an overdrive condition occurs when the
output and/or input ranges are exceeded. The recovery
time varies based on whether the input or output is overdriven and by how much the ranges are exceeded. The
CLC2005 will typically recover in less than 20ns from an
overdrive condition. Figure 4 shows the CLC2005 in an
overdriven condition.
©2004-2009 CADEKA Microcircuits LLC Comlinear CLC2005 Dual, Low Cost, +2.7V to 5.5V, 260MHz Rail-to-Rail Amplifier
The CLC2005 is a single supply, general purpose, voltagefeedback amplifier fabricated on a complementary bipolar
process using a patent pending topography. It features a
rail-to-rail output stage and is unity gain stable. Both gain
bandwidth and slew rate are insensitive to temperature.

Driving Capacitive Loads
The Frequency Response vs. CL plot on page 6, illustrates
the response of the CLC2005. A small series resistance
(Rs) at the output of the amplifier, illustrated in Figure 5,
will improve stability and settling performance. Rs values
in the Frequency Response vs. CL plot were chosen to
achieve maximum bandwidth with less than 1dB of peaking. For maximum flatness, use a larger Rs.

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 to
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
■Place
the 6.8μF capacitor within 0.75 inches of the
power pin
Rev 1B
■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
