At unity gain (G=1), these amplifiers offer 550kHz of bandwidth. They consume only 0.5mA of supply current over the entire power supply operating range. The CLC1050, CLC2050, and CLC4050 are specifically designed to operate from single or dual supply voltages. The COMLINEAR CLC1050, CLC2050, and CLC4050 offer a common mode voltage range that includes ground and a wide output voltage swing. The combination of low-power, high supply voltage range, and low supply current make these amplifiers well suited for many general purpose applications and as alternatives to several industry standard amplifiers on the market today.

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. 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. +Vs Input 6.8μF 0.1μF + Output - RL 0.1μF Rg Rf 6.8μF Figure 1.

For instance, Rloadeff in figure 3 would be calculated as: RL || (Rf + Rg) 0.1μF + Vsupply = VS+ - VSPower delivered to a purely resistive load is: Rf Figure 2. Typical Inverting Gain Circuit +Vs PD = Psupply - Pload Psupply = Vsupply × IRMS supply 0.1μF In order to determine PD, the power dissipated in the load needs to be subtracted from the total power delivered by the supplies. Supply power is calculated by the standard power equation. 6.8μF 0.1μF + TJunction = TAmbient + (ӨJA × PD) Where TAmbient is the temperature of the working environment. G = 1 + (Rf/Rg) -Vs 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. G=1 Figure 3. Unity Gain Circuit 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: Comlinear CLC1050, CLC2050, CLC4050 Low Power, 3V to 36V, Single, Dual, Quad Amplifiers Application Information Rev 1A ©2007-2009 CADEKA Microcircuits LLC www.cadeka.com 10 Data Sheet (VLOAD)RMS = VPEAK / √2 ( ILOAD)RMS = ( VLOAD)RMS / Rloadeff The dynamic power is focused primarily within the output stage driving the load. This value can be calculated as: RS (Ω) -3dB BW (kHz) 1nF 0 485 5nF 0 390 10nF 0 260 100 0 440 Assuming the load is referenced in the middle of the power rails or Vsupply/2.

In general, reducing RS will increase bandwidth at the expense of additional overshoot and ringing. Overdrive Recovery 2 1.5 Table 1: Recommended RS vs. CL 60 80 Ambient Temperature (°C) 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 CLCx050 will typically recover in less than 30ns from an overdrive condition. Figure 6 shows the CLC1050 in an overdriven condition. Figure 4. Maximum Power Derating 4 VIN = 1.25Vpp G=5 3.5 3 Input Voltage (V) 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.

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