These amplifiers are designed to operate on +3V to +5V, or 5V supplies. The input voltage range extends 300mV below the negative rail and 0.9V below the positive rail. The XR8051, XR8052, and XR8054 offer superior dynamic performance with a 260MHz small signal bandwidth and 190V/s slew rate. The combination of low power, high output current drive, and rail-to-rail performance make these amplifiers well suited for battery-powered systems and video applications. The combination of low cost and high performance make the XR8051, XR8052, and XR8054 suitable for high volume applications in both consumer and industrial applications such as video surveillance and distribution systems, professional and IPC cameras, active filter circuits, coaxial cable drivers, and electronic white boards.

They feature a rail-to-rail output stage and is unity gain stable. Input 0.1F + Output RL 0.1F The common mode input range extends to 300mV below ground and to 0.9V 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. 6.8F Figure 3: Unity Gain Circuit +Vs 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. Figure 4 shows the typical non-inverting gain circuit for single supply applications.

The recovery time varies based on whether the input or output is overdriven and by how much the ranges are exceeded. The XR8051, XR8052, and XR8054 will typically recover in less than 20ns from an overdrive condition. Figure 5 shows the XR8052 in an overdriven condition. 6.8F 6 Input Rg OUTPUT 4 0.1F + 2 Output Voltage (V) R1 RL 0.1F 6.8F -Vs Rf 0 INPUT -2 -4 G = - (Rf/Rg) Vs = +/-5V_RL=2K_AV=+5 For optimum input offset voltage set R1 = Rf || Rg -6 0 100 200 300 400 500 600 700 800 900 1,000 Time (ns) Figure 2: Typical Inverting Gain Circuit Figure 5: Overdrive Recovery (c) 2007-2014 Exar Corporation 17 / 27 exar.com/XR8051 Rev 1B XR8051, XR8052, XR8054 Power Dissipation Power dissipation should not be a factor when operating under the stated 2k 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. Assuming the load is referenced in the middle of the power rails or Vsupply/2. The XR8051 is short circuit protected. However, this may not guarantee that the maximum junction temperature (+150C) is not exceeded under all conditions. Figure 6 shows the maximum safe power dissipation in the package vs. the ambient temperature for the packages available. 2.5 Maximum Power Dissipation (W) Maximum power levels are set by the absolute maximum junction rating of 170C. 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.

Maximum Power Derating Supply power is calculated by the standard power equation. Psupply = Vsupply x IRMSsupply 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, 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 7. Rloadeff in Figure 3 would be calculated as: Input + 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: Rf Output CL RL Rg Figure 7. Addition of RS for Driving Capacitive Loads Table 1 provides the recommended RS for various capacitive loads. The recommended RS values result in approximately <1dB peaking in the frequency response. CL (pF) (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 (c) 2007-2014 Exar Corporation Rs RS () -3dB BW (MHz) 22pF 0 120 47pF 15 80 100pF 15 65 492pF 6.5 40 Table 1: Recommended RS vs. CL 18 / 27 exar.com/XR8051 Rev 1B XR8051, XR8052, XR8054 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. Layout Considerations General layout and supply bypassing play major roles in high frequency performance. Exar 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.
