general description the max4480Cmax4483 low-cost, general-purpose op amps offer rail-to-rail outputs, draw only 50a of quies - cent current, and operate from a single +2.5v to +5.5v supply. for additional power conservation, the max4481 offers a low-power shutdown mode that reduces supply current to 0.5a (max) and puts the amplifiers output in a high-impedance state. these devices are unity-gain stable with capacitive loads up to 400pf. the max4480C max4483 are specified to +125c, making them suitable for use in a variety of harsh environments. the max4480 is a single amplifier offered in a tiny 5-pin sc70 package. the max4481 is a single amplifier with a low-power shutdown mode that reduces supply current to < 0.5a and comes in a 6-pin sc70 package. the max4482 is a dual amplifier and comes in the space-sav - ing 8-pin sot23 or max? package. the max4483 is a quad amplifier and comes in a 14-pin tssop package. all devices are specified for operation across the -40c to +125c automotive temperature range. applications single-supply zero-crossing detectors instruments and terminals portable communications electronic ignition modules infrared receivers sensor signal detection features single +2.5v to +5.5v supply voltage range 50a quiescent current per amplifier 0.5a (max) shutdown mode (max4481) available in space-saving packages ? 5-pin sc70 (max4480) ? 6-pin sc70 (max4481) ? 8-pin sot23 (max4482) 105db av ol with 5k load 0.005% thd with 100k load rail-to-rail output voltage swing 3.0ma of sink and source load current unity-gain stable up to c load = 400pf pin configurations continued at end of data sheet. max is a registered trademark of maxim integrated products, inc. 19-1809; rev 4; 5/14 + denotes a lead(pb)-free/rohs-compliant package. t = tape and reel. part no. of amplifiers per package shutdown mode max4480 1 no max4481 1 yes max4482 2 no max4483 4 no part temp range pin- package top mark max4480 axk+t -40c to +125c 5 sc70 abu max4480auk+t -40c to +125c 5 sot23 adpj max4481 axt+t -40c to +125c 6 sc70 aan max4481aut+t -40c to +125c 6 sot23 aaos max4481mxt/pr3+ -55c to +110c 6 sc70 aee max4482 aka+t -40c to +125c 8 sot23 aaej max4482asa+ -40c to +125c 8 so max4482aua+ -40c to +125c 8 fmax max4483 asd+ -40c to +125c 14 so max4483aud+ -40c to +125c 14 tssop in+ in- 12 3 54 out v ss v dd + + in+ in- 12 3 65 4 out shdn v ss v dd max4480 max4481 sc70-5/sot23-5 sc70-6/sot23-6 max4480Cmax4483 single/dual/quad, low-cost, single-supply, rail-to-rail op amps with shutdown pin conigurations selector guide ordering information evaluation kit available downloaded from: http:///

detailed description rail-to-rail output stage the max4480Cmax4483 can drive a 5k load and still typically swing within 80mv of the supply rails. figure 1 shows the max4480 output voltage swing configured with a v = +10v/v. driving capacitive loads driving a capacitive load can cause instability in many op amps, especially those with low quiescent current. the max4480Cmax4483 are unity-gain stable for a range of capacitive loads to above 400pf. figure 2 shows the max4480 response with an excessive capacitive load. adding a series resistor between the output and the load capacitor (figure 3) improves the circuits response by isolating the load capacitance from the op amps output. figure 1. rail-to-rail output operation pin name function max4480 max4481 max4482 max4483 1 1 in+ noninverting ampliier input 3 3 ina+ noninverting ampliier input a 5 5 inb+ noninverting ampliier input b 10 inc+ noninverting ampliier input c 12 ind+ noninverting ampliier input d 2 2 4 11 v ss negative supply. connect to ground for single-supply operation. use a 0.01f bypass capacitor to gnd. 3 3 in- inverting ampliier input 2 2 ina- inverting ampliier input a 6 6 inb- inverting ampliier input b 9 inc- inverting ampliier input c 13 ind- inverting ampliier input d 4 4 out ampliier output 1 1 outa ampliier output a 7 7 outb ampliier output b 8 outc ampliier output c 14 outd ampliier output d 5 6 8 4 v dd positive supply. use a 0.01f bypass capacitor to gnd. 5 shdn active-low shutdown input. connect to v dd for normal operation. do not leave loating. 1v/div 100s/div max4480Cmax4483 single/dual/quad, low-cost, single-supply, rail-to-rail op amps with shutdown www.maximintegrated.com maxim integrated 7 pin description downloaded from: http:///
applications information shutdown mode the max4481 features a low-power shutdown mode. when shdn goes low, the supply current drops to 0.05a (typ) and the output enters a high-impedance state. pull shdn high to enable the amplifier. do not leave shdn floating. figure 4 shows the shutdown waveform.power-up the max4480Cmax4483 outputs typically settle within 50s after power-up. figure 5 shows the output voltage on power-up and power-down. power supplies and layout the max4480Cmax4483 operate from a single +2.5v to +5.5v power supply. bypass the power supply with a 0.1f capacitor to ground. good layout techniques optimize performance by decreasing the amount of stray capacitance at the op amps inputs and outputs. to decrease stray capacitance, minimize trace lengths by placing external components close to the op amps pins. figure 2. small-signal transient response with excessive capacitive load figure 4. shutdown waveform figure 3. capacitive-load-driving circuit figure 5. power-up/down waveform 20s/div 50mv/div c l = 1nf r iso c l max4480max4481 max4482 max4483 400s/div 2v/div r l = 10m ? to v ss , c l = 25pf 4s/div out 1v/div v dd 2v/div max4480Cmax4483 single/dual/quad, low-cost, single-supply, rail-to-rail op amps with shutdown www.maximintegrated.com maxim integrated 8 chip information process: bicmos downloaded from: http:///
