general description the max9040?ax9043 and max9050?ax9053 fea- ture combinations of low-power comparators and preci- sion voltage references. their operating voltage range makes them ideal for both +3v and +5v systems. the max9040/max9041/max9050/max9051 have a single comparator and reference consuming only 40? of supply current. the max9042/max9043/max9052/ max9053 have dual comparators and one reference, and consume only 55? of supply current. low-voltage operation and low supply current make these devices ideal for battery-operated systems. the comparators feature rail-to-rail inputs and out- puts, with a common-mode input voltage range that extends 250mv beyond the supply rails. input bias cur- rent is typically 1.0pa, and input offset voltage is typi- cally 0.5mv. internal hysteresis ensures clean output switching, even with slow-moving input signals. the output stage features a unique design that limits supply current surges while switching, virtually eliminating sup- ply glitches typical of many other comparators. this design also minimizes overall power consumption under dynamic conditions. the comparator outputs have rail-to-rail push-pull output stages that sink and source up to 8ma. the propagation delay is 400ns, even with the low operating supply current. the reference output voltage is set to 2.048v in the max9040?ax9043 and to 2.500v in the max9050 max9053. these devices are offered in two grades: an a grade with 0.4% initial accuracy and 6ppm/? tempco, and a b grade with 1% initial accuracy and 100ppm/? tempco. the voltage reference features a proprietary curvature-correction circuit and laser- trimmed thin-film resistors. the series-mode references can sink or source up to 500? of load current. applications precision battery management window comparators ir receivers level translators digital line receivers features comparator + precision reference in sot23 +2.5v to +5.5v single-supply operation (max9040?ax9043) low supply current (max9040/max9050) 40? quiescent 50? with 100khz switching 400ns propagation delay rail-to-rail inputs rail-to-rail output stage sinks and sources 8ma internal ?mv hysteresis voltage reference offers ?.4% max initial accuracy (a grade) 6ppm/? typ temperature coefficient (a grade) stable for 0nf to 4.7nf capacitive loads ordering information continued at end of data sheet. * future product?ontact factory for availability. max9040?ax9043/max9050?ax9053 micropower, single-supply, sot23 comparator + precision reference ics ________________________________________________________________ maxim integrated products 1 19-1569; rev 2; 4/00 ordering information rail-to-rail is a registered trademark of nippon motorola, ltd. typical operating circuit appears at end of data sheet. functional diagrams appear at end of data sheet. selector guide appears at end of data sheet. v ee ref in+ 15 v cc out max9040 max9050 sot23-5 top view 2 34 pin configurations pin configurations continued at end of data sheet. pin- package 5 sot23-5 5 sot23-5 6 sot23-6 6 sot23-6 8 so 8 so 8 ?ax 8 ?ax 8 so 8 so 10 ?ax 10 ?ax -40? to +85? -40? to +85? -40? to +85? -40? to +85? -40? to +85? -40? to +85? -40? to +85? -40? to +85? -40? to +85? -40? to +85? -40? to +85? -40? to +85? temp. range part max9040 aeuk-t max9040beuk-t max9041 aeut-t* max9041beut-t* max9041aesa* max9041besa* max9042 aeua max9042beua max9042aesa max9042besa max9043 aeub max9043beub top mark adnv adnx aahf aahh for free samples and the latest literature, visit www.maxim-ic.com or phone 1-800-998-8800. for small orders, phone 1-800-835-8769.

detailed description the max9040?ax9043 and max9050?ax9053 fea- ture single/dual, low-power, low-voltage comparators and a precision voltage reference. they operate from a single +2.5v to +5.5v (max904_) or +2.7v to +5.5v (max905_) supply. the single comparators with refer- ence (max9040/max9041/max9050/max9051) con- sume only 40? of supply current, while the dual comparators with reference (max9042/max9043/ max9052/max9053) consume only 55? of supply cur- rent. their common-mode input range extends 0.25v beyond each rail. internal hysteresis ensures clean out- put switching, even with slow-moving input signals. the output stage employs a unique design that mini- mizes supply current surges while switching, virtually eliminating the supply glitches typical of many other comparators. large internal output drivers allow rail-to- rail output swing that can sink and source up to 8ma of current. the precision reference uses a proprietary curvature- correction circuit and laser-trimmed thin-film resistors, resulting in a temperature coefficient of less than 30ppm/? over the extended temperature range and initial accuracy of 0.4% (a grade). the reference output voltage is set to 2.048v in the max9040?ax9043 and to 2.500v in the max9050?ax9053. comparator input stage circuitry the devices?input common-mode range extends from (v ee - 0.25v) to (v cc + 0.25v). these comparators may operate at any differential input voltage within these lim- its. input bias current is typically 1.0pa if the input volt- age is between the supply rails. comparator inputs are protected from overvoltage by internal body diodes connected to the supply rails. as the input voltage exceeds the supply rails, these body diodes become forward biased and begin to conduct. consequently, bias currents increase exponentially as the input volt- age exceeds the supply rails. comparator output stage circuitry the comparators in these devices contain a unique output stage capable of rail-to-rail operation with loads up to 8ma. many comparators consume orders-of-mag- nitude more current during switching than during steady-state operation. however, with this family of com- parators, the supply current change during an output transition is extremely small. the typical operating characteristics graph supply current vs. switching frequency shows the minimal supply current increase as the output switching frequency approaches 1mhz. this characteristic reduces the need for power-supply filter capacitors to reduce glitches created by compara- tor switching currents. another advantage realized in high-speed, battery-powered applications is a substan- tial increase in battery life. applications information additional hysteresis these comparators have ?mv internal hysteresis. additional hysteresis can be generated with two resis- tors using positive feedback (figure 1). use the follow- ing procedure to calculate resistor values: 1) calculate the trip points of the comparator using these formulas: and v th is the threshold voltage at which the comparator switches its output from high to low as v in rises above the trip point. v tl is the threshold voltage at which the comparator switches its output from low to high as v in drops below the trip point. 2) the hysteresis band will be: v hys = v th - v tl = v cc r rr 2 12 + ? ? ? ? ? ? vv r rr tl ref =? + ? ? ? ? ? ? 1 2 12 vv vvr rr th ref cc ref =+ ?
