general description the max4180 family of current-feedback amplifiers combines high-speed performance, low distortion, and excellent video specifications with ultra-low-power operation in miniature packages. they operate from ?.25v to ?.5v dual supplies, or from a single +5v supply. they require only 1ma of supply current per amp- lifier while delivering up to ?0ma of output current drive. the max4180/max4182/max4183/max4186 are compensated for applications with a closed-loop gain of +2 (6db) or greater, and provide a -3db band- width of 240mhz and a 0.1db bandwidth of 70mhz. the max4181/max4184/max4185/max4187 are com- pensated for applications with a +1 (0db) or greater gain, and provide a -3db bandwidth of 270mhz and a 0.1db bandwidth of 60mhz. the max4180?ax4187 feature 0.08%/0.03 differen- tial gain and phase errors, a 20ns settling time to 0.1%, and a 450v/? slew rate, making them ideal for high- performance video applications. the max4180/ max4181/ max4183/max4185 have a low-power shut- down mode that reduces power-supply current to 135? and places the outputs in a high-impedance state. this feature makes them ideal for multiplexing applications. the single max4180/max4181 are offered in space- saving 6-pin sot23 packages. ________________________applications portable/battery-powered high-definition video/multimedia systems surveillance video broadcast and high-definition professional tv systems cameras high-speed a/d buffers video switching/ multiplexing ccd imaging systems medical imaging features ? ultra-low supply current: 1ma per amplifier ? shutdown mode: outputs placed in high-z supply current reduced to 135? ? operate from a single +5v supply or dual ?v supplies ? wide bandwidth: 270mhz -3db small-signal bandwidth (max4181/84/85/87) ? 450v/? slew rate ? fast, 20ns settling time to 0.1% ? excellent video specifications: gain flatness to 70mhz (max4180/82/83/86) 0.08%/0.03 differential gain/phase ? low distortion: -73dbc sfdr (f c = 5mhz, v out = 2vp-p) ? available in tiny surface-mount packages: 6-pin sot23 (max4180/81) 10-pin ?ax (max4183/85) 16-pin qsop (max4186/87) max4180?ax4187 single/dual/quad, 270mhz, 1ma, sot23, current-feedback amplifiers with shutdown ________________________________________________________________ maxim integrated products 1 19-1221; rev 2; 8/98 5 v ee in- in+ 1 6 v cc shdn out max4180 max4181 sot23-6 single top view 2 3 4 pin configurations selector guide pin configurations continued at end of data sheet. aaab sot top mark 8 so 6 sot23-6 pin- package temp. range -40? to +85? -40? to +85? max4180esa max4180 eut-t part ordering information continued at end of data sheet. ordering information a v 3 1 no 4 max4187 a v 3 2 no 4 max4186 a v 3 1 a v 3 1 a v 3 2 a v 3 2 a v 3 1 a v 3 2 optimized for yes no yes no yes yes shutdown mode 2 2 2 2 1 1 no. of amps max4184 max4185 part max4182 max4183 max4180 max4181 for free samples & the latest literature: http://www.maxim-ic.com, or phone 1-800-998-8800. for small orders, phone 1-800-835-8769.

max4180?ax4187 single/dual/quad, 270mhz, 1ma, sot23, current-feedback amplifiers with shutdown ______________________________________________________________________________________ 15 detailed description the max4180?ax4187 are ultra-low-power current- feedback amplifiers featuring bandwidths up to 270mhz, 0.1db gain flatness to 90mhz, and low differ- ential gain (0.08%) and phase (0.03? errors. these amplifiers achieve ultra-high bandwidth-to-power ratios with low distortion, wide signal swing, and excellent load-driving capabilities. they are optimized for ?v supplies but also operate from a single +5v supply while consuming only 1ma per amplifier. with ?0ma output current drive capability, the devices achieve low distortion even while driving 150 loads. wide bandwidth, low power, low differential phase and gain error, and excellent gain flatness make the max4180?ax4187 ideal for use in portable video equipment such as cameras, video switchers, and other battery-powered applications. their two-stage design provides higher gain and lower distortion than conventional single-stage, current-feedback topolo- gies. this feature, combined with fast settling time, makes these devices suitable for buffering high-speed analog-to-digital converters (adcs). the max4180/max4181/max4183/max4185 have a low-power shutdown mode that is activated by driving the amplifiers? shdn input low. placing them in shut- down reduces quiescent supply current to 135? (typ) and places amplifier outputs in a high-impedance state. these amplifiers can be used to implement a high-speed multiplexer by connecting together the out- puts of multiple amplifiers and controlling the shdn inputs to enable one amplifier and disable all the oth- ers. the disabled amplifiers present very little load (0.1? leakage current and 4pf capacitance) to the active amplifiers?output. note that the feedback net- work impedance of all the disabled amplifiers must be considered when calculating the total load on the active amplifier output. application information theory of operation the max4180?ax4187 are current-feedback ampli- fiers, 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 decreas- es at approximately 6db per octave. analyzing the follower with gain, as shown in figure 1, 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 @ 160 . 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: layout and power-supply bypassing the max4180?ax4187 have an rf bandwidth and, consequently, require careful board layout, including the possible use of constant-impedance microstrip or stripline techniques. to realize the full ac performance of these high-speed amplifiers, pay careful attention to power-supply bypass- ing and board layout. the pc board should have at least two layers: a signal and power layer on one side, and a large, low-impedance ground plane on the other side. the ground plane should be as free of voids as possible. with multilayer boards, locate the ground plane on a layer that incorporates no signal or power traces. regardless of whether a constant-impedance board is used, observe the following guidelines when designing the board: do not use wire-wrap boards. they are too inductive. do not use breadboards. they are too capacitive. do not use ic sockets. they increase parasitic capacitance and inductance. use surface-mount components rather than through- hole components. they give better high-frequency performance, have shorter leads, and have lower parasitic reactances. keep lines as short and as straight as possible. v v out in ( / ) ==+ grr fg 1 v in r f r g v out t 2 r in +1 +1 max4180-max4187 figure 1. current-feedback amplifier
