general description the max4414?ax4419 operational amplifiers com- bine high-speed performance, low distortion, and ultra- low supply current. consuming just 1.6ma of supply current per amplifier, these devices operate from a sin- gle +2.7v to +5.5v supply, have rail-to-rail outputs, and exhibit a common-mode input voltage range that extends from 100mv below ground to within 1.5v of the positive supply rail. the max4414/max4416/max4418 single/dual/quad op amps are unity-gain stable and achieve a 400mhz -3db bandwidth with a 200v/? slew rate. the max4415/ max4417/max4419 single/dual/quad op amps are compensated for closed-loop gains of +5v/v or greater and achieve a 150mhz -3db bandwidth with a 470v/? slew rate. the combination of high-speed, ultra-low power, and low-distortion makes the max4414 max4419 ideal for low-power/low-voltage, high-speed portable systems such as video, communications, and instrumentation. the max4414/max4415 single and max4416/ max4417 dual amplifiers are available in space-saving 8-pin ?ax and so packages, while the max4418/ max4419 quad amplifiers are available in a 14-pin tssop package. ________________________applications battery-powered instruments portable communications keyless entry systems cellular telephones video line drivers baseband applications features ultra-low 1.6ma supply current single +3v/+5v operation high speed 400mhz -3db bandwidth (max4414/max4416/max4418) 200v/? slew rate (max4414/max4416/max4418) 150mhz -3db bandwidth (max4415/max4417/max4419) 470v/? slew rate (max4415/max4417/max4419) rail-to-rail outputs input common-mode range extends beyond v ee low differential gain/phase: 0.03%/0.15 low distortion at 5mhz (max4414/max4416/max4418) -93dbc sfdr 0.003% total harmonic distortion low cost max4414?ax4419 low-power, +3v/+5v, 400mhz single-supply op amps with rail-to-rail outputs ________________________________________________________________ maxim integrated products 1 part no. of amps minimum gain (v/v) -3db bandwidth (mhz) slew rate (v/s) max4414 1 1 400 200 max4415 1 5 150 470 max4416 2 1 400 200 max4417 2 5 150 470 max4418 4 1 400 200 max4419 4 5 150 470 part temp. range pin-package max4414 eua -40 c to +85 c8 max max4414esa -40 c to +85 c 8 so max4415 eua -40 c to +85 c8 max MAX4415ESA -40 c to +85 c 8 so _____________________selector guide 19-1837; rev 0; 10/00 for price, delivery, and to place orders, please contact maxim distribution at 1-888-629-4642, or visit maxim? website at www.maxim-ic.com. ordering information rail-to-rail is a registered trademark of nippon motorola, ltd. pin configurations appear at end of data sheet. 1.30 1.45 1.40 1.35 1.55 1.50 1.75 1.70 1.65 1.60 1.80 2.7 3.1 3.5 3.9 4.3 4.7 5.1 5.5 supply current vs. supply voltage (per amplifier) max4414 toc01 supply voltage (v) supply current (ma) ordering information continued at end of data sheet. typical operating characteristic

max4414?ax4419 low-power, +3v/+5v, 400mhz single-supply op amps with rail-to-rail outputs ______________________________________________________________________________________ 15 _______________detailed description the max4414 max4419 single-supply, rail-to-rail, volt- age-feedback amplifiers achieve high slew rates and bandwidths, while consuming only 1.6ma of supply current per amplifier. excellent harmonic distortion and differential gain/phase performance make these ampli- fiers an ideal choice for a wide variety of video and rf signal-processing applications. internal feedback around the output stage ensures low open-loop output impedance, reducing gain sensitivity to load variations. this feedback also produces demand-driven current bias to the output transistors. rail-to-rail outputs, ground-sensing input the max4414 max4419 input common-mode range extends from (v ee - 0.1v) to (v cc - 1.5v) with excellent common-mode rejection. beyond this range, the ampli- fier output is a nonlinear function of the input, but does not undergo phase reversal or latchup. the output swings to within 105mv of either power-sup- ply rail with a 1k ? load. input ground sensing and rail- to-rail output substantially increase the dynamic range. with a symmetric input in a single +5v application, the input can swing 3.6vp-p, and the output can swing 4.6vp-p with minimal distortion. output capacitive loading and stability the max4414 max4419 are optimized for ac perfor- mance. they are not designed to drive highly reactive loads. such loads decrease phase margin and may produce excessive ringing and oscillation. the use of an isolation resistor eliminates this problem (figure 1). figure 2 is a graph of the optimal isolation resistor (r iso ) vs. capacitive load. the small-signal gain vs. frequency with capacitive load and no isolation resistor graph in the typical operating characteristics shows how a capacitive load causes excessive peaking of the amplifier s frequency response if the capacitor is not isolated from the ampli- fier by a resistor. a small isolation resistor (usually 20 ? to 30 ? ) placed before the reactive load prevents ring- ing and oscillation. at higher capacitive loads, ac per- formance is controlled by the interaction of the load capacitance and the isolation resistor. the small-signal gain vs. frequency with capacitive load and 22 ? isolation resistor graph shows the effect of a 22 ? isola- tion resistor on closed-loop response. pin description pin max4414 max4415 max4416 max4417 max4418 max4419 name function 1, 5, 8 n.c. no connection. not internally connected. 3 in+ amplifier noninverting input 3 3 ina+ amplifier a noninverting input 5 5 inb+ amplifier b noninverting input 10 inc+ amplifier c noninverting input 12 ind+ amplifier d noninverting input 2 in- amplifier inverting input 2 2 ina- amplifier a inverting input 6 6 inb- amplifier b inverting input 9 inc- amplifier c inverting input 13 ind- amplifier d inverting input 4 4 11 v ee negative power supply 6 out amplifier output 1 1 outa amplifier a output 7 7 outb amplifier b output 8 outc amplifier c output 14 outd amplifier d output 784v cc positive power supply
max4414?ax4419 low-power, +3v/+5v, 400mhz single-supply op amps with rail-to-rail outputs 16 ______________________________________________________________________________________ coaxial cable and other transmission lines are easily driven when properly terminated at both ends with their characteristic impedance. driving back-terminated transmission lines essentially eliminates the line s capacitance. ___________applications information choosing resistor values unity-gain configuration the max4414/max4416/max4418 are internally com- pensated for unity gain. when configured for unity gain, the devices require a 24 ? feedback resistor (r f ). this resistor improves ac response by reducing the q of the parallel lc circuit formed by the parasitic feedback capacitance and inductance. inverting and noninverting configurations select the gain-setting feedback (r f ) and input (r g ) resistor values that best fit the application. large resis- tor values increase voltage noise and interact with the amplifier s input and pc board capacitance. this can generate undesirable poles and zeros and decrease bandwidth or cause oscillations. for example, a nonin- verting gain-of-two configuration (r f = r g ) using 1k ? resistors, combined with 1.8pf of amplifier input capac- itance and 1pf of pc board capacitance, causes a pole at 114mhz. since this pole is within the amplifier bandwidth, it jeopardizes stability. reducing the 1k ? resistors to 100 ? extends the pole frequency to 1.14ghz, but could limit output swing by adding 200 ? in parallel with the amplifier s load resistor. note: for high gain applications where output offset voltage is a consideration, choose r s to be equal to the parallel combination of r f and r g (figures 3a and 3b): r rr rr s fg fg = + v out v out = [1+ (r f / r g )] v in in r f r 0 r s r g figure 3a. noninverting gain configuration v out in r s r f r o r g v out = (r f / r g ) v in figure 3b. inverting gain configuration v out v in r bin r iso r f c l r g figure 1. driving a capacitive load through an isolation resistor figure 2. capacitive load vs. isolation resistance 10 16 14 12 18 20 22 24 26 28 30 0 400 200 600 800 1000 c load (pf) r iso ( ? )
