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 2 illustrates the CLC2005 frequency response with both 1kΩ and 2kΩ feedback resistors. Magnitude (1dB/div) 1 10 100 Frequency (MHz) Figure 2: Frequency Response vs. Rf 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.

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.

When evaluating only one channel, complete the following on the unused channel: 1.Ground the non-inverting input. 2.Short the output to the inverting input. Evaluation Board Information Time (20ns/div) Figure 4: Overdrive Recovery 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. + - Description Products CEB006 Dual Channel, Dual Supply 8 lead SOIC CLC2005SO8 Evaluation board schematics and layouts are shown in Figure 6 and Figure 7.
