general description the max4188/max4189/MAX4190 are low-power, current-feedback video amplifiers featuring fast dis- able/enable times and low switching transients. the triple max4188 and the single MAX4190 are optimized for applications with closed-loop gains of +2v/v (6db) or greater and provide a -3db bandwidth of 200mhz and 185mhz, respectively. the triple max4189 is opti- mized for closed-loop applications with gains of +1v/v (0db) or greater and provides a 250mhz -3db band- width. these amplifiers feature 0.1db gain flatness up to 80mhz with differential gain and phase errors of 0.03% and 0.05? these features make the max4188 family ideal for video applications. the max4188/max4189/MAX4190 operate from a +5v single supply or from ?.25v to ?.5v dual supplies. these amplifiers consume only 1.5ma per amplifier and are capable of delivering ?5ma of output current, making them ideal for portable and battery-powered equipment. the max4188/max4189/m ax4190 have a high-speed disable/enable mode that isolates the inputs, places the outputs in a high-impedance state, and reduces the supply current to 450? per amplifier. each amplifier can be disabled independently. high off isolation, low switching transient, and fast enable/disable times (120ns/35ns) allow these amplifiers to be used in a wide range of multiplexer applications. a settling time of 22ns to 0.1%, a slew rate of up to 350v/?, and low distortion make these devices useful in many general- purpose, high-speed applications. the max4188/max4189 are available in a tiny 16-pin qsop package, and the MAX4190 is available in a space-saving 8-pin ?ax package. applications high-definition surveillance video high-speed switching/multiplexing portable/battery-powered video/multimedia systems high-speed analog-to-digital buffers medical imaging high-speed signal processing professional cameras ccd imaging systems rgb distribution amplifiers features ? low supply current: 1.5ma per amplifier ? fast enable/disable times: 120ns/35ns ? very low switching transient: 45mv p-p ? high speed 200mhz -3db small-signal bandwidth (max4188, a vcl +2) 250mhz -3db small-signal bandwidth (max4189, a vcl +1) 185mhz -3db small-signal bandwidth (MAX4190, a vcl +2) ? high slew rate 350v/ s (max4188, a vcl +2) 175v/ s (max4189, a vcl +1) ? excellent video specifications 85mhz -0.1db gain flatness (MAX4190) 30mhz -0.1db gain flatness (max4189) differential gain/phase errors 0.03%/0.05 (max4188) ? low-power disable mode inputs isolated, outputs placed in high-z supply current reduced to 450 a per amplifier ? fast settling time of 22ns to 0.1% ? low distortion 70db sfdr (f c = 5mhz, v o = 2v p-p , max4188) ? available in space-saving packages 16-pin qsop (max4188/max4189) 8-pin max (MAX4190) max4188/max4189/MAX4190 single/triple, low-glitch, 250mhz, current- feedback amplifiers with high-speed disable ________________________________________________________________ maxim integrated products 1 19-1369; rev 1; 2/07 ordering information continued at end of data sheet. ordering information pin configuration appears at end of data sheet. 8-pin ?ax/so 1 a v +2v/v MAX4190 14-pin so, 16-pin qsop 3 a v +1v/v max4189 14-pin so, 16-pin qsop 3 a v +2v/v max4188 pin-package amplifiers per pkg. optimized for: part selector guide for pricing, delivery, and ordering information, please contact maxim/dallas direct! at 1-888-629-4642, or visit maxim? website at www.maxim-ic.com. ?ax is a registered trademark of maxim integrated products, inc. part temp range pin- package pkg code max4188 esd+ -40? to +85? 14 so s14-1 max4188eee+ -40? to +85? 16 qsop e16-1 + denotes lead-free package. evaluation kit available

max4188/max4189/MAX4190 single/triple, low-glitch, 250mhz, current- feedback amplifiers with high-speed disable 16 ______________________________________________________________________________________ amplifiers achieve very high isolation from input to output (65db at 10mhz), and the outputs are placed into a high- impedance state. these amplifiers achieve low switch- ing-transient glitches (<45mv p-p ) when switching between enable and disable modes. fast enable/disable times (120ns/35ns), along with high off-isolation and low switching transients, allow these devices to be used as high-performance, high-speed multiplexers. this is achieved by connecting the outputs of multiple amplifiers together and controlling the disable inputs to enable one amplifier and disable all others. the disabled ampli- fiers present a very light load (1? leakage current and 3.5pf capacitance) to the active amplifier? output. the feedback network impedance of all the disabled ampli- fiers must still be considered when calculating the total load on the active amplifier output. figure 1 shows an application circuit using the max4188 as a 3:1 video mul- tiplexer. the disable_ logic threshold is typically v cc - 2.5v, independent of v ee . for a single +5v supply or dual ?v supplies, the disable inputs are cmos-logic com- patible. the amplifiers default to the enabled mode if the disable pin is left unconnected. if the disable pin is left floating, take proper care to ensure that no high-frequency signals are coupled to this pin, as this may cause false triggering. applications information theory of operation the max4188/max4189/MAX4190 are current-feedback amplifiers, and their open-loop transfer function is expressed as a transimpedance, ? v out / ? i in , or t z . the frequency behavior of the open-loop transimpedance is similar to the open-loop gain of a voltage-mode feedback amplifier. that is, it has a large dc value and decreases at approximately 6db per octave. analyzing the follower with gain, as shown in figure 2, yields the following transfer function: v out / v in = g x [(t z (s) / t z (s) + g x (r in + r f )] where g = a vcl = 1 + (r f / r g ), and r in = 1/g m ? 300 ? . at low gains, g x r in < r f . therefore, the closed-loop bandwidth is essentially independent of closed-loop gain. similarly t z > r f at low frequencies, so that: v v out in ( / ) ==+ grr fg 1 v in r g r in t z r f +1 +1 v out max4188 max4189 MAX4190 figure 2. current-feedback amplifier amp1 6 7 5 560 ? 75 ? v in 1 560 ? 1.0 f 1.0 f 0.1 f 4 11 +5v -5v 0.1 f 87 ? amp2 13 14 12 9 10 disable2 disable3 disable1 560 ? 75 ? v in 2 560 ? v out 87 ? 75 ? 75 ? cable 8 123 560 ? 75 ? v in 3 560 ? 87 ? max4188 amp3 figure 1. high-speed 3:1 video multiplexer

(r f || r g =280 ? ), and r s = 37.5 ? , gives the following: calculating the total output noise in a similar manner yields: with a 200mhz system bandwidth, this calculates to 68? rms (approximately 408? p-p , choosing the six- sigma value). video line driver the max4188/max4189/MAX4190 are well suited to drive coaxial transmission lines when the cable is termi- nated at both ends (figure 5). cable frequency response can cause variations in the signal? flatness. see table 1 for optimum r f and r g values. driving capacitive loads the max4188/max4189/m ax4190 are optimized for ac performance. reactive loads decrease phase mar- gin and may produce excessive ringing and oscillation. unlike most high-speed amplifiers, the max4188/ max4189/MAX4190 are tolerant of capacitive loads up to 50pf. capacitive loads greater than 50pf may cause ringing and oscillation. figure 6a shows a circuit that eliminates this problem. placing the small (usually 15 ? to 33 ? ) isolation resistor, r s , before the reactive load prevents ringing and oscillation. at higher capaci- tive loads, the interaction of the load capacitance and isolation resistor controls ac performance. figures 6b and 6c show the max4188 and max4189 frequency response with a 100pf capacitive load. note that in each case, gain peaking is substantially reduced when the 20 ? resistor is used to isolate the capacitive load from the amplifier output. e xx xx x ehz n out n out () () . ./ =+ () ? ? ? ? + ? ? ? ? + ? ? ? ? = ? ?? 11 410 375 510 280 210 48 12 2 12 2 9 2 nv v xx x x x v out out = ? ? ? ? + ? ? ? ? + ? ? ? ? ? ? ? ? ? ? + () = ?? ? 1 10 37 5 2 10 280 15 10 11 41 66 3 . . .mv e r r x ir ir r e n out f g ns nf g n () || =+ ? ? ? ? ? ?
