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.

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. Figures 1, 2, and 3 illustrate typical circuit configurations for non-inverting, inverting, and unity gain topologies for dual supply applications. They show the recommended bypass capacitor values and overall closed loop gain equations. +Vs 0.1μF + Output - RL 0.1μF Rg Rf 6.8μF -Vs R1 Input Rg 6.8μF 0.1μF + G = 1 + (Rf/Rg) 0.1μF 6.8μF -Vs Input RL Pload = ((VLOAD)RMS2)/Rloadeff G = - (Rf/Rg) For optimum input offset voltage set R1 = Rf || Rg 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) 6.8uF Output - RL 0.1uF 6.8uF -Vs Vsupply = VS+ - VS- Power delivered to a purely resistive load is: Rf 0.1uF + PD = Psupply - Pload Psupply = Vsupply × IRMS supply Figure 2. Typical Inverting Gain Circuit +Vs In order to determine PD, the power dissipated in the load needs to be subtracted from the total power delivered by the supplies. Supply power is calculated by the standard power equation. Output - TJunction = TAmbient + (ӨJA × PD) Where TAmbient is the temperature of the working environment. Figure 1. Typical Non-Inverting Gain Circuit +Vs 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.

Table 1: Recommended RS vs. CL 20 40 Overdrive Recovery 60 80 Ambient Temperature (°C) 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. Figure 4.
