? 2014 exar corporation 9 / 16 exar.com/xr1009 rev 1b xr1009, xr2009 application information general description the xr1009 and xr2009 are a single supply, general purpose, voltage-feedback ampliers fabricated on a complementary bipolar process. the xr1009 offers 35mhz unity gain bandwidth, 27v/s slew rate, and only 208a supply current. it features a rail-to-rail output stage and is unity gain stable. the design utilizes a patent pending topology that provides increased slew rate performance. the common mode input range extends to 300mv below ground and to 1.2v 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. the design uses a darlington output stage. the output stage is short circuit protected and offers soft saturation protection that improves recovery time. figures 1, 2, and 3 illustrate typical circuit congurations 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. + - 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 0.1f 6.8f out in +v s + r g figure 4: single supply non-inverting gain circuit
? 2014 exar corporation 10 / 16 exar.com/xr1009 rev 1b xr1009, xr2009 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 150c. 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 rmssupply 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 specied 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 xr1009 is short circuit protected. however, this may not guarantee that the maximum junction temperature (+150c) is not exceeded under all conditions. figure 5 shows the maximum safe power dissipation in the package vs. the ambient temperature for the packages available. 0 0.5 1 1.5 -40 -20 0 20 40 60 80 100 120 maximum power dissipation (w) ambient temperature ( c) msop-8 soic-8 tsot-5 figure 5. 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 amplier and the load to help improve stability and settling performance. refer to figure 6. + - r f input output r g r s c l r l figure 6. addition of r s for driving capacitive loads overdrive recovery for an amplier, 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 overdriven and by how much the ranges are exceeded. the xr1009, and xr2009 will typically recover in less than 20ns from an overdrive condition.
