?2013 exar corporation 17/23 rev 1a application information general description the XR8051, xr8052, and xr8054 are single supply, general purpose, voltage-feedback amplifers fabricated on a complementary bipolar process using a patent pending topography. they feature a rail-to-rail output stage and is unity gain stable. the common mode input range extends to 300mv below ground and to 0.9v below v s . 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. the output stage is short circuit protected and offers soft saturation protection that improves recovery time. figures 1, 2, and 3 illustrate typical circuit confgurations 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 applicaitons. + - r f 0.1f 6.8f output g = 1 + ( r f /r g ) input +v s -v s r g 0.1f 6.8f r l figure 1. typical non-inverting gain circuit + - r f 0.1f 6.8f output g = - ( r f /r g ) for optimum input offset voltage set r 1 = r f || r g input +v s -v s 0.1f 6.8f r l r g r 1 figure 2. typical inverting gain circuit + - 0.1f 6.8f output g = 1 input +v s -v s 0.1f 6.8f r l figure 3. unity gain circuit + - r f 0.01f 6.8f out in +v s + r g figure 4. single supply non-inverting gain circuit overdrive recovery for an amplifer, an overdrive condition occurs when the output and/or input ranges are exceeded. the recovery time varies based on whether the input or output is over - driven 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 2 0 2 6 0 100 200 500 600 700 ojh 7lphq s = +/ - 5v_rl=2k_av=+5 input output ljxuh2yhugulyh5hfyhu data sheet XR8051, xr8052, xr8054 low cost, high speed rail-to-rail amplifers rev 1a free datasheet http://www.datasheet-pdf.com/
?2013 exar corporation 18/23 rev 1a 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 its intended operating range. maximum power levels are set by the absolute maximum junction rating of 170c. to calculate the junction temperature, the package thermal resistance value theta ja (? ja ) is used along with the total die power dissipation. t junction = t ambient + (? ja p d ) where t ambient is the temperature of the working environment. in order to determine p d , the power dissipated in the load needs to be subtracted from the total power delivered by the supplies. p d = p supply - p load supply power is calculated by the standard power equation. p supply = v supply i rms supply v supply = v s+ - v s- power delivered to a purely resistive load is: p load = ((v load ) rms 2 )/rload eff the effective load resistor (rload eff ) will need to include the effect of the feedback network. for instance, rload eff in figure 3 would be calculated as: r l || (r f + r g ) 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, p d can be found from p d = p quiescent + p dynamic - p load quiescent power can be derived from the specifed i s values along with known supply voltage, v supply . load power can be calculated as above with the desired signal amplitudes using: (v load ) rms = v peak / 2 ( i load ) rms = ( v load ) rms / rload eff the dynamic power is focused primarily within the output stage driving the load. this value can be calculated as: p dynamic = (v s+ - v load ) rms ( i load ) rms assuming the load is referenced in the middle of the power rails or v supply /2. the XR8051 is short circuit protected. however, this may not guarantee that the maximum junction temperature (+170c) 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. 0 0.5 1 1.5 2 2.5 -40 -20 0 20 40 60 80 100 120 maximum power dissipation (w) ambient temperature ( c) sot23 - 5 soic - 8 msop - 8 soic - 14 tssop - 14 figure 6. 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, r s , between the amplifer and the load to help improve stability and settling performance. refer to figure 7. + - r f input output r g r s c l r l figure 7. addition of r s for driving capacitive loads data sheet XR8051, xr8052, xr8054 low cost, high speed rail-to-rail amplifers rev 1a free datasheet http://www.datasheet-pdf.com/
?2013 exar corporation 19/23 rev 1a table 1 provides the recommended r s for various capacitive loads. the recommended r s values result in approximately <1db peaking in the frequency response. cl (pf) rs (?) -3db bw (mhz) 22pf 0 120 47pf 15 80 100pf 15 65 492pf 6.5 40 table 1: recommended r s vs. c l for a given load capacitance, adjust r s to optimize the tradeoff between settling time and bandwidth. in general, reducing r s 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. c adeka 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. evaluation board information the following evaluation boards are available to aid in the testing and layout of these devices: evaluation board # products ceb002 XR8051 in sot23 ceb003 XR8051 in soic evaluation board # products ceb006 xr8052 in soic ceb010 xr8052 in msop ceb018 xr8054 in soic evaluation board schematics evaluation board schematics and layouts are shown in figures 10-18. these evaluation boards are built for dual- supply operation. follow these steps to use the board in a single-supply application: 1. short -vs to ground. 2. use c3 and c4, if the -v s pin of the amplifer is not directly connected to the ground plane. figure 8. ceb002 & ceb003 schematic data sheet XR8051, xr8052, xr8054 low cost, high speed rail-to-rail amplifers rev 1a free datasheet http://www.datasheet-pdf.com/
