They show the recommended bypass capacitor values and overall closed loop gain equations. +Vs 6.8F 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 Supply power is calculated by the standard power equation. Psupply = Vsupply x IRMSsupply Input 0.1F + Vsupply = VS+ - VSOutput RL 0.1F Rg 6.8F -Vs Power delivered to a purely resistive load is: Rf Pload = ((Vload)RMS2)/Rloadeff G = 1 + (Rf/Rg) Figure 1: Typical Non-Inverting Gain Circuit +Vs R1 Input Rg + The effective load resistor (Rloadeff) will need to include the effect of the feedback network. For instance, Rloadeff in Figure 2 would be calculated as: 6.8F RL || (Rf + Rg) 0.1F 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 Output RL 0.1F 6.8F -Vs Rf G = - (Rf/Rg) For optimum input offset voltage set R1 = Rf || Rg 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: Figure 2: Typical Inverting Gain Circuit (Vload)RMS = Vpeak / 2 ( Iload)RMS = ( Vload)RMS / Rloadeff Power Dissipation Power dissipation should not be a factor when operating under the stated 500 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. Maximum power levels are set by the absolute maximum junction rating of 150C. To calculate the junction temperature, the package thermal resistance value ThetaJA (JA) is used along with the total die power dissipation. TJunction = TAmbient + (JA x PD) (c) 2007-2014 Exar Corporation The dynamic power is focused primarily within the output stage driving the load. This value can be calculated as: PDynamic = (VS+ - Vload)RMS x ( Iload)RMS Assuming the load is referenced in the middle of the power rails or Vsupply/2. Figure 3 shows the maximum safe power dissipation in the package vs. the ambient temperature for the packages available. 12 / 17 exar.com/CLC1003 Rev 1D CLC1003 Overdrive Recovery Maximum Power Dissipation (W) 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 ranges are exceeded. The CLC1003 will typically recover in less than 20ns from an overdrive condition. Figure 5 shows the CLC1003 in an overdriven condition. 1.5 SOIC-8 1 0.5 TSOT-6 3 0 -40 -20 0 20 40 60 80 100 2 VIN = .8Vpp G=5 120 Ambient Temperature (C) 2 2 1 Input Voltage (V) 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 4. 1 Input 1 0 0 Output -1 -1 Output Voltage (V) Figure 3.

Addition of RS for Driving Capacitive Loads The CLC1003 is capable of driving up to 300pF directly, with no series resistance. Directly driving 500pF causes over 4dB of frequency peaking, as shown in the plot on page 6. Table 1 provides the recommended RS for various capacitive loads. The recommended RS values result in 1dB peaking in the frequency response. The Frequency Response vs. CL plots, on page 6, illustrate the response of the CLC1003. There are three sources of offset contribution to consider; input bias current, input bias current mismatch, and input offset voltage. The input bias currents are assumed to be equal with and additional offset current in one of the inputs to account for mismatch. The bias currents will not affect the offset as long as the parallel combination of Rf and Rg matches Rt. Refer to Figure 6. - Rt CL (pF) RS () -3dB BW (MHz) 500 10 27 1000 7.5 20 3000 4 15 Table 1: Recommended RS vs. CL For a given load capacitance, adjust RS to optimize the tradeoff between settling time and bandwidth. In general, reducing RS will increase bandwidth at the expense of additional overshoot and ringing. (c) 2007-2014 Exar Corporation +Vs Rf Rg IN CLC1003 + RL -Vs Figure 6: Circuit for Evaluating Offset The first place to start is to determine the source resistance. If it is very small an additional resistance may need to be added to keep the values of Rf and Rg to practical levels. For this analysis we assume that Rt is the total resistance present on the non-inverting input. This gives us one equation that we must solve: 13 / 17 exar.com/CLC1003 Rev 1D CLC1003 Rt = Rg||Rf The complete equation can be simplified to: This equation can be rearranged to solve for Rg: 2 v o Rg = (Rt * Rf) / (Rf - Rt) The other consideration is desired gain (G) which is: ( 2 ) ( ) = 3 4kT G RT + enG ( + 2 in RT 2 ) It's easy to see that the effect of amplifier voltage noise is proportionate to gain and will tend to dominate at large gains. The other terms will have their greatest impact at large Rt values at lower gains. G = (1 + Rf/Rg) By plugging in the value for Rg we get Rf = G * Rt And Rg can be written in terms of Rt and G as follows: Rg = (G * Rt) / (G - 1) The complete input offset equation is now only dependent on the voltage offset and input offset terms given by: VI OS = 2 2 Layout Considerations General layout and supply bypassing play major roles in high frequency performance. Exar 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: ( VIO ) + (IOS RT) And the output offset is: VO OS = G 2 2 ( V IO ) + (I OS RT ) Include 6.8F and 0.1F ceramic capacitors for power supply decoupling Place the 6.8F capacitor within 0.75 inches of the power pin Place the 0.1F 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.
