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 its intended operating range. 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) G = - (Rf/Rg) For optimum input offset voltage set R1 = Rf || Rg Figure 2. Typical Inverting Gain Circuit 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 ©2009-2013 Exar Corporation 11/14 Rev 1B Rev 1B Rg Figure 4. Single Supply Non-Inverting Gain Circuit CLC1020 General Purpose, Rail to Rail Output Ampli ier The CLC1020 is a single supply, general purpose, voltagefeedback amplifier fabricated on a CMOS process. The CLC1020 offers 2.1MHz gain bandwidth product, 2.7V/μs slew rate, and only 127μA supply current. It features a rail to rail output stage and is unity gain stable. The common mode input range extends to 400mV below ground and to 700mV 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. The output stage is short circuit protected and offers “soft” saturation protection that improves recovery time. Figures 1, 2, and 3 illustrate typical circuit configurations for noninverting, inverting, and unity gain topologies for dual supply applications. They show the recommended bypass capacitor values and overall closed loop gain equations. Figure 4 shows the typical non-inverting gain circuit for single supply applications 6.8µF Data Sheet the supplies. Input PD = Psupply - Pload + Supply power is calculated by the standard power equation. - 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 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: 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. Overdrive Recovery 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 CLC1020 and will typically recover in less than 5us from an overdrive condition. Figure 6 shows the CLC1020 in an overdriven condition. (VLOAD)RMS = VPEAK / √2 Rev 1B The dynamic power is focused primarily within the output stage driving the load. This value can be calculated as: ( ILOAD)RMS = ( VLOAD)RMS / Rloadeff Ω PDYNAMIC = (VS+ - VLOAD)RMS × ( ILOAD)RMS Assuming the load is referenced in the middle of the power rails or Vsupply/2. The CLC1020 is short circuit protected. However, this may not guarantee that the maximum junction temperature (+150°C) is not exceeded under all conditions. μs) Figure 6. Overdrive Recovery Layout Considerations 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.
