This high performance exceeds the requirements of high-definition television (HDTV) and other multimedia applications. These COMLINEAR high-performance amplifiers also provide ample output current to drive multiple video loads. The COMLINEAR CLC1004, CLC1014, and CLC3004 are designed to operate from ±5V or +5V supplies. The CLC1004 and CLC3004 offer a fast enable/ disable feature to save power. While disabled, the outputs are in a highimpedance state to allow for multiplexing applications. The combination of high-speed, low-power, and excellent video performance make these amplifiers well suited for use in many general purpose, high-speed applications including video line driving and imaging applications.

They show the recommended bypass capacitor values and overall closed loop gain equations. +Vs 6.8μF perature, 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.

For instance, Rloadeff in figure 3 would be calculated as: 0.1μF Rg -Vs 6.8μF RL Rf G = 1 + (Rf/Rg) Figure 1. Typical Non-Inverting Gain Circuit +Vs 6.8μF 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.

Typical Inverting Gain Circuit 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 ( 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 × ( ILOAD)RMS Assuming the load is referenced in the middle of the power rails or Vsupply/2. Figure 3 shows the maximum safe power dissipation in the package vs. the ambient temperature for the packages available. Power Dissipation Power dissipation should not be a factor when operating under the stated 1000 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.

Maximum Power Derating 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 CLCx004 will typically recover in less than 20ns from an overdrive condition. Figure 5 shows the CLC1004 in an overdriven condition. 3 3 2 Input Comlinear CLC1004, CLC1014, CLC3004 Single and Triple, 750MHz Amplifiers with Disable 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 4.

CaDeKa has evaluation boards to use as a guide for high frequency layout and as aid in device testing and characterization. Follow the steps below as a basis for high frequency layout: • Include 6.8µF and 0.1µF ceramic capacitors for power supply decoupling • Place the 6.8µF capacitor within 0.75 inches of the power pin • Place the 0.1µF 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. www.cadeka.com Table 1 provides the recommended RS for various capacitive loads. The recommended RS values result in
