Comlinear CLC2057 Dual, Low Noise, Operational Amplifier
General Description
The COMLINEAR CLC2057 is a low noise, dual voltage feedback amplifier that is internally frequency compensated to provide unity gain stability. The CLC2057 offers over 13MHz of unity gain bandwidth and excellent (110dB) CMRR, PSRR, and open loop gain. The CLC2057 also features low input voltage noise (4nV/Hz) and low distortion (0.0005%) making it well suited for audio applications such as audio filtering. Other applications include industrial measurement tools, pre-amplifiers, and other circuits that require wellmatched channels. The COMLINEAR CLC2057 is designed to operate over a wide power supply voltage range, 2V to 18V (4V to 36V). It utilizes an industry standard dual amplifier pin-out and is available in a Pb-free, RoHS compliant SOIC-8 package.

Application Information
Basic Operation Figures 1 and 2 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 6.8F
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 150C. To calculate the junction temperature, the package thermal resistance value ThetaJA (JA) is used along with the total die power dissipation. TJunction = TAmbient + (JA x 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.

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 x ( ILOAD)RMS Assuming the load is referenced in the middle of the power rails or Vsupply/2. Figure 4 shows the maximum safe power dissipation in the package vs. the ambient temperature for the packages available.

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 CLC2057 will typically recover in less than 5s from an overdrive condition. Figure 6 shows the CLC2057 in an overdriven condition.

Figure 6. Overdrive Recovery Layout Considerations General layout and supply bypassing play major roles in high frequency performance. CaDeKa has evaluation boards to use as a guide for high frequency layout and as an aid in device testing and characterization. Follow the steps below as a basis for high frequency layout: * Include 6.8F and 0.1F ceramic capacitors for power supply decoupling * Place the 6.8F capacitor within 0.75 inches of the power pin * Place the 0.1F capacitor within 0.1 inches of the power pin * Remove the ground plane under and around the part, especially near the input and output pins to reduce parasitic capacitance * Minimize all trace lengths to reduce series inductances Refer to the evaluation board layouts below for more information.
Figure 4. Maximum Power Derating
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 5.
