They show the recommended bypass capacitor values and overall closed loop gain equations. +Vs 6.8μF perature, 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 Supply power is calculated by the standard power equation. Output Comlinear CLC1003 Low Distortion, Low Offset, RRIO Amplifier Input + - 0.1μF Psupply = Vsupply × IRMS supply Vsupply = VS+ - VSPower delivered to a purely resistive load is: 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: 0.1μF Rg -Vs 6.8μF RL Rf G = 1 + (Rf/Rg) Figure 1. Typical Non-Inverting Gain Circuit +Vs 6.8μF RL || (Rf + Rg) 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 G = - (Rf/Rg) For optimum input offset voltage set R1 = Rf || Rg R1 Input Rg + - 0.1μF Output 0.1μF 6.8μF -Vs RL Rf Figure 2. Typical Inverting Gain Circuit 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: (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: PDYNAMIC = (VS+ - VLOAD)RMS × ( 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. Rev 1A Power Dissipation Power dissipation should not be a factor when operating under the stated 300 ohm 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 150°C.

In general, reducing RS will increase bandwidth at the expense of additional overshoot and ringing.

Maximum Power Derating 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 CLCx003 will typically recover in less than 20ns from an overdrive condition. Figure 5 shows the CLC1003 in an overdriven condition. 3 2 VIN = .8Vpp G=5 2 2 1 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.

Addition of RS for Driving Capacitive Loads The CLC1003 family of amplifiers 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
