GENERAL DESCRPTON The or5 elmnates the need for an output buffer n applcatons whch requre hgh loaddrvng capablty coupled wth premum amplfer performance. The output stage can drve :t5ma nto son loads. n addton, the output s stable wth capactve loads of up to 1nF. Ths load drvng ablty makes the OP5 deal for amplfyng small sgnals for transmsson through long cables. The amplfer features openloop voltage gan of over 1 mllon wth commonmode rejecton and power supply rejecton of greater than 126dB (AlE grades). SMPLFEDSCHEMATC m EXTERNAL COMPENSATON r'h COMP lcom V.

2 RNRLOGDEVCESfRXONDEnRNDHOTLNE Page 3 OP5 The Or5 s stable for closedloop gans above 5. and can be externally compensated for closedloop gans n the range of 5 to 5. The amplfer s desgned for use n hghgan and/or hghoutputcurrent applcatons. For example, an OO7 coupled wth an output buffer can be replaced by a sngle or5 amplfer. onmplanted superbeta transstors, combned wth a patented nput bas current cancellaton crcut, provde an nput bas current of only 5nA and nput offset current of 1nA. Over the full mltary temperature range, nput bas current and nput offset current for an Agrade devce does not exceed BnAand 3nA. respectvely. nput offset voltages are trmmed to a maxmum of 2SpV(AlE grades) and 1OllV(B/F grades) usng PMl's enerappng technque. Ths low offset elmnates the need for an offset trmpot n most applcatons. Lowvoltagenose, typcally 4.SnV JH at 1kH,s acheved n the orso wth mnmum sacrfce of nput protecton. Overload protecton s provded by nput resstors of 2Sn and emtterbase dodes. The nput resstors provde current lmt protecton aganst dfferental nputs of up to j:1v;and the dodes prevent avalanche breakdown whch could degrade the 18.'os' and matchng of the nput stage transstors. External resstors can be added to the nput to guard aganst hgher nput voltages; however. the added resstors wll degrade nose voltage performance. When mnmum nose voltage s requred, source resstance should be kept below a few hundred ohms. Separate outputstage power supply pns are provded on the OP5 to allow control of devce power dsspaton and output voltage swng. The maxmum voltage whch may be appled across the power supply pns s j:18v.the guaranteed specfcatons are based on operatng both stages at j:1sv;however. there s mnmal effect on DC performance when the man amplfer s operated at :t15vand the output stage s operated at a reduced voltage. When operatng both the man amplfer and the output stage at the same voltages. the correspondng power supply pns may be ted together. Decouplng capactors are recommended between the power supply pns and analog ground. t s necessary to use decoupng capactors On each power supply pn when operatng the output stage at supply voltages less than the amplfer supply voltage. Do not operate the outputstage negatve power supply pn at a more negatve voltage than the negatve supply pn (V). A thermallysymmetrc de layout, whch dffers from other op amp desgns by the postonng of more devces along the center lne.provdes the OP5 wth a thermal drft of less than O.3lV/oC.Ths layout feature s crtcalto the mantenance of hgh openloop gan when drvng largecurrent loads and dsspatng hundreds of mllwatts n the devce. The use of a heatsnk s recommended to reduce nternal temperature rse when operatng at hgh output power levels. The useof standard dualnlnepackageheatsnkswllhelp to dsspate heat to the envronment. Other technques. such as the use of external voltagedroppng resstors. allow heat to be dsspated outsde of the package. See Fgure 5,Drvng SOHLoads, n the applcatons secton. Athermalshutdown crclt protects the OPSOfrom overdsspaton. When the de temperature reaches approxmately 165 C. the output stage automatcally shuts down. The amplfer nput stage remans fully operatonal. thereby protectng the sgnal source from any loadng changes caused by a complete shutdown. COMPENSATON FOR GANS BETWEEN 5 AND 5 The Or5 can be compensated for nvertng gans between 5 and 5 usng a seres resstor and capactor.

The OPSO, operatng wthout feedback, drves a second gan stage whch generates a TTLcompatble output sgnal. Schottkyclamp dodes prevent overdrvng of the longtaled transstor par and stop saturaton of the output transstor. Power supply voltage s set to 5V to lower the quescent power dsspaton and mnme thermal feedback due to output stage dsspaton. Operatng from:tsvsupplesalso reduces the OPSOrse and fall tmes as the output slews over a reduced voltage range. Ths, n turn, reduces the output response tme. t s common practce wth voltage comparators to ground one nput termnal and to use a sngleended nput The hstorc reason s poor commonmode rejecton on the nput stage. n contrast, the OPSO has very hgh commonmode rejecton and s capable of detectng mcrovolt level dfferences n the presence of large commonmode sgnals.
