?2009-2013 exar corporation 9/15 rev 1d application information general description the clc1009 family are a single supply, general purpose, voltage-feedback amplifers fabricated on a complementary bipolar process. the clc1009 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 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 + - 0.1uf 6.8uf output g = 1 input +v s -v s 0.1uf 6.8uf 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 data sheet c omlinear clc1009, CLC2009 0.2ma, low cost, 35mhz rail-to-rail amplifers rev 1d
?2009-2013 exar corporation 10/15 rev 1d 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 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 clc1009 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 1 2 20 0 20 60 80 0pp3rhusr ph7hpshuuh sot23 - 5 soic - 8 msop - 8 sot23 - 6 uh0pp3rhuhu usfhr fuhh sh ho h rs h r fsfh or f fh u sh h iuhthf uhsrh sroh oh hru 8h huh uhfh 5 s , between the amplifer 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 data sheet c omlinear clc1009, CLC2009 0.2ma, low cost, 35mhz rail-to-rail amplifers rev 1d
?2009-2013 exar corporation 11/15 rev 1d overdrive recovery an overdrive condition is defned as the point when either one of the inputs or the output exceed their specifed voltage range. overdrive recovery is the time needed for the amplifer 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 clc1009 and CLC2009 will typically recover in less than 20ns from an overdrive condition. 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 clc1009 in sot23 ceb003 clc1009 in soic ceb006 CLC2009 in soic evaluation board schematics evaluation board schematics and layouts are shown in figures 8-14. 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 figure 9. ceb002 top view data sheet c omlinear clc1009, CLC2009 0.2ma, low cost, 35mhz rail-to-rail amplifers rev 1d
