Amplifiers15TI develops high-speed signal conditioningproducts using state-of-the-art processes thatgive leading-edge performance. Used inhigh-speed signal chains and analog-to-digitaldrive circuits, high-speed amps are broadlydefined as any amplifier having at least50MHz of bandwidth and at least 100V/µsslew rate. High-speed amps from TI come inseveral different types and supplyvoltage options.Design ConsiderationsVoltage-feedback type—the mostcommonly used amp and the basic buildingblock of most analog signal chains such asgain blocks, filtering, level shifting, buffering,etc. Most voltage-feedback amps are unitygainstable, though some are decompensatedto provide wider bandwidth, faster slew rateand lower noise.Current-feedback type—most commonlyseen in video or DSL line driver applications, ordesigns where extremely fast slew rateis needed.Fully differential amplifier (FDA)—the fullydifferential input and output topology has theprimary benefit of reducing even orderharmonics, thereby reducing total harmonicdistortion. The FDA also rejects common-modecomponents in the signal and provides a largeroutput swing to the load relative to singleendedamplifiers. Fully differential amplifiersare well-suited to driving analog-to-digitalconverters. A V COM pin sets the outputcommon-mode voltage required by newer,single-supply, ADCs.FET-Input (or CMOS) amplifiers—have higherinput impedance than typical bipolar ampsand are more useful to interfacing to highimpedance sources, such as photodiodes intransimpedance circuits.Video amplifiers—can be used in anumber of different ways, but generally arein the signal path for amplifying, buffering,filtering or driving video lines. The specificationsof most interest are differential gainand differential phase. Current-feedbackamps are typically used in video applications,because of their combination of high slewrate and excellent output drive at lowquiescent power.High-Speed AmplifiersFixed and variable gain—these amps haveeither a fixed gain, or a variable gain that canbe set either digitally with a few control pins,or linearly with a control voltage. Fixed-gainamplifiers are fixed internally with gainsetting resistors. Variable gain amplifiers canhave different gain ranges, and can also bedifferential input and/or output.Packaging—high-speed amplifiers typicallycome in surface-mount packages, becauseparasitics of DIP packages can limit performance.Industry standard surface-mountpackages (SOIC, MSOP, TSSOP and QFN) handlethe highest speed requirements. For bandwidthsapproaching 1GHz and higher, theQFN package decreases inductance andcapacitance.Evaluation boards—high-speed amps have anassociated fully populated evaluation module(EVM) or an unpopulated printed circuit board(PCB). EVMs are a very important part ofhigh-speed amplifier evaluation, since layout iscritical to design success. To make layoutsimple, Gerber files for the EVMs are available.See page 101 for more information.➔Voltage FeedbackCurrent FeedbackHigh-Speed < 500MHz (GBW Product)THS4001THS4011/4012THS4051/4052THS4081/4082THS4041/4042OPA820/OPA4820OPA2613OPA2614OPA842OPA2652OPA2822THS4271OPA690/2690/3690OPA890/OPA2890OPA2889Fully DifferentialTHS4120/4121THS4130/4131THS4140/4141THS4500/4501THS4502/4503THS4509THS4508THS4511THS4513THS4520FET or CMOS InputOPA656OPA657 (G > 7)OPA355/2355/3355OPA356/2356OPA354/2354/4354OPA357/2357OPA358/OPA360/OPA361OPA300/OPA2300OPA301/OPA2301THS4631OPA380/OPA2380Low Voltage ≤ 3.3VTHS4120/21OPA355/2355/3355OPA356/2356OPA354/2354/4354OPA357/2357OPA300/OPA2300OPA301/OPA2301OPA830/OPA2830/OPA4830OPA832/OPA2832/OPA3832Low Noise ≤ 3nV/ HzTHS4031/4032OPA2822THS4130/4131THS4271OPA300/OPA301OPA820/OPA4820OPA842OPA843 (G > 3)OPA846/OPA2846 (G > 7)OPA847 (G > 12)OPA358OPA820/OPA4820Variable and Fixed GainTHS7530VCA2612/2613/2614/2616/2618VCA810VCA8613/VCA8617VCA2615/VCA2617OPA860OPA861BUF602BUF634OPA615OPA693/OPA3693General Purpose+5V to ±5V OperationalOPA683/2683OPA684/2684/3684/4684OPA691/2691/3691OPA692/3692 (G = 2 or ±1)OPA2677THS3201/02OPA694/OPA2694OPA2674General Purpose±5V to ±15V OperationalTHS3112/15THS3122/25THS3110/11THS3120/1THS3091/95THS3092/96THS6184Very High-Speed > 500MHz (GBW Products) Rail-to-Rail Input or OutputOPA843OPA847OPA846/OPA2846THS4271THS4302High-speed amplifiers selection tree.OPA355/2355/3355OPA356/2356THS4222/4226OPA354/2354/4354OPA357/2357OPA358/OPA360/OPA361OPA830/OPA2830/OPA4830OPA832/OPA2832/OPA3832Voltage Limiting OutputOPA698OPA699 (G ≥ 4)Very High-Speed > 500MHzOPA695THS3201/THS3202OPA694/OPA2694Preview devices appear in BLUE.New devices appear in RED.Texas Instruments 3Q 2007Amplifier and Data Converter Selection Guide
