The CLC1008 offers 75MHz unity gain bandwidth, 50V/μs slew rate, and only 505μA supply current. It features a rail-to-rail output stage and is unity gain stable. 6.8uF Rev 2C Data Sheet Power Dissipation ( ILOAD)RMS = ( VLOAD)RMS / Rloadeff 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 CLC1008 is short circuit protected. However, this may not guarantee that the maximum junction temperature (+150°C) is not exceeded under all conditions. Figure 6 shows the maximum safe power dissipation in the package vs. the ambient temperature for the packages available. 2 SOIC-8 Maximum Power Dissipation (W) 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. The dynamic power is focused primarily within the output stage driving the load. This value can be calculated as: MSOP-8 1.5 1 0.5 SOT23-6 SOT23-5 Supply power is calculated by the standard power equation. 0 -40 -20 0 20 40 60 80 Ambient Temperature (°C) Psupply = Vsupply × IRMS supply Figure 6. Maximum Power Derating 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: RL || (Rf + Rg) 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 7. Input + - 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: (VLOAD)RMS = VPEAK / √2 ©2009-2013 Exar Corporation Rs Rf Rev 2C 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 Driving Capacitive Loads Output CL RL Rg Figure 7. Addition of RS for Driving Capacitive Loads Table 1 provides the recommended RS for various capacitive loads. The recommended RS values result in 11/16 Comlinear CLC1008, CLC2008 0.5mA, Low Cost, 75MHz Rail-to-Rail Amplifiers Power dissipation should not be a factor when operating under the stated 1k 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.

In general, reducing RS will increase bandwidth at the expense of additional overshoot and ringing. 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 CLC1008 and CLC2008 will typically recover in less than 20ns from an overdrive condition. Figure 8 shows the CLC1008 in an overdriven condition.
