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.

They show the recommended bypass capacitor values and overall closed loop gain equations. +Vs 6.8μF Power Dissipation Power dissipation should not be a factor when operating under the stated 2k 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. 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) 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. Psupply = Vsupply × IRMS supply Output Comlinear CLC1050, CLC2050, CLC4050 Low Power, 3V to 36V, Single, Dual, Quad Amplifiers Input + - 0.1μF Output 0.1μF RL Rf G = 1 + (Rf/Rg) Rg -Vs 6.8μF Figure 1. Typical Non-Inverting Gain Circuit +Vs 6.8μF R1 Input Rg + - 0.1μF 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) 0.1μF 6.8μF -Vs RL Rf G = - (Rf/Rg) For optimum input offset voltage set R1 = Rf || Rg Figure 2. Typical Inverting Gain Circuit +Vs 6.8μF Input + - 0.1μF Output RL 0.1μF 6.8μF -Vs 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: G=1 Figure 3.

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.

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 CLCx050 will typically recover in less than 30ns from an overdrive condition. Figure 6 shows the CLC1050 in an overdriven condition. 4 3.5 4 3.5 3 Input Maximum Power Dissipation (W) 1.5 SOT23-6 1 0.5 SOT23-5 0 -40 -20 0 20 40 60 80 Ambient Temperature (°C) Figure 4.
