These amplifiers use only 208μA of supply current and are designed to operate from a supply range of 2.5V to 5.5V (±1.25 to ±2.75). The input voltage range extends 300mV below the negative rail and 1.2V below the positive rail. The CLC1009 and CLC2009 offer high bipolar performance at a low CMOS price. They offer superior dynamic performance with a 35MHz small signal bandwidth and 27V/μs slew rate. The combination of lowpower, high bandwidth, and rail-to-rail performance make the CLC1009 and CLC2009 well suited for battery-powered communication/ computing systems.

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.

Single Supply Non-Inverting Gain Circuit Comlinear CLC1009, CLC2009 0.2mA, Low Cost, 35MHz Rail-to-Rail Amplifiers The CLC1009 family are a single supply, general purpose, voltage-feedback amplifiers fabricated on a complementary bipolar process. The CLC1009 offers 35MHz unity gain bandwidth, 27V/μs slew rate, and only 208μA supply current. It features a rail-to-rail output stage and is unity gain stable. 6.8μF Rev 1D ©2009-2013 Exar Corporation 9/15 Rev 1D Data Sheet Maximum power levels are set by the absolute maximum junction rating of 150°C. To calculate the junction temperature, 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 PDYNAMIC = (VS+ - VLOAD)RMS × ( ILOAD)RMS Assuming the load is referenced in the middle of the power rails or Vsupply/2. The CLC1009 is short circuit protected. However, this may not guarantee that the maximum junction temperature (+150°C) is not exceeded under all conditions. Figure 5 shows the maximum safe power dissipation in the package vs. the ambient temperature for the packages available. 2 SOIC-8 MSOP-8 1.5 1 0.5 SOT23-6 SOT23-5 0 Supply power is calculated by the standard power equation. -40 -20 Psupply = Vsupply × IRMS supply Pload = ((VLOAD)RMS2)/Rloadeff The effective load resistor (Rloadeff) will need to include the effect of the feedback network. For instance, Rloadeff in Figure 3 would be calculated as: RL || (Rf + Rg) 40 60 80 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 6. Input + Rs Rf PD = PQuiescent + PDynamic - PLoad Output CL Rev 1D 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 20 Figure 5. Maximum Power Derating Vsupply = VS+ - VSPower delivered to a purely resistive load is: 0 Ambient Temperature (°C) RL Rg 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: Figure 6.

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. The dynamic power is focused primarily within the output stage driving the load. This value can be calculated as: Maximum Power Dissipation (W) Power Dissipation Rev 1D Data Sheet 1. Short -Vs to ground. 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 CLC1009 and CLC2009 will typically recover in less than 20ns from an overdrive condition. 2. Use C3 and C4, if the -VS pin of the amplifier is not directly connected to the ground plane. Comlinear CLC1009, CLC2009 0.2mA, Low Cost, 35MHz Rail-to-Rail Amplifiers 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, especially near the input and output pins to reduce parasitic capacitance Figure 8.
