max9092/max9093/max9094/max9095 general-purpose, low-voltage, dual/quad, tiny pack comparators 9 detailed description the max9092/max9093/max9094/max9095 are low- cost, general-purpose comparators that have a single- supply +1.8v to +5v operating voltage range. the common-mode input range extends from -0.1v below the negative supply to within +0.8v of the positive supply. they require approximately 65 f a per comparator with a 5v supply and 50 f a with a 2.7v supply. the max9093/max9095 have 2mv of hysteresis for noise immunity. this significantly reduces the chance of output oscillations even with slow moving input signals. the ics are ideal for automotive applications because they oper - ate from -40 n c to +125 n c. see the typical operating characteristics . applications information hysteresis many comparators oscillate in the linear region of opera - tion because of noise or undesired parasitic feedback. this tends to occur when the voltage on one input is equal or very close to the voltage on the other input. the max9093/max9095 have internal hysteresis to counter parasitic effects and noise. the hysteresis in a comparator creates two trip points: one for the rising input voltage and one for the falling input voltage ( figure 1 ). the difference between the trip points is the hysteresis. when the comparators input voltages are equal, the hysteresis effectively causes one comparator input to move quickly past the other, thus taking the input out of the region where oscillation occurs. this provides clean output transitions for noisy, slow-moving input signals. additional hysteresis can be generated with two resis - tors using positive feedback ( figure 2 ). use the following procedure to calculate resistor values: 1) find output voltage when output is high: v out(high) = v dd - i load x r l 2) find the trip points of the comparator using these formulas: v th = v ref + ((v out(high) - v ref )r2)/(r1 + r2) v tl = v ref (1 - (r2/(r1 + r2))) where v th is the threshold voltage at which the compara - tor switches its output from high to low as v in rises above the trip point, and 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. 3) the hysteresis band is: v hyst = v th - v tl = v dd (r2/(r1 + r2)) in this example, let v dd = 5v, v ref = 2.5v, i load = 50na, and r l = 5.1k i . v out(high) = 5.0v - (50 x 10 -9 x 5.1 x 10 3 i ) 5.0v v th = 2.5 + 2.5(r2/(r1 + r2)) v tl = 2.5(1 - (r2/(r1 + r2))) select r2. in this example, choose 1k i . select v hyst . in this example, choose 50mv. solve for r1. v hyst = v out(high) (r2/(r1 + r2))v 0.050v = 5(1000/(r1 + 1000))v where r1 100k i , v th = 2.525v, and v tl = 2.475v figure 1. threshold hysteresis band (not to scale) figure 2. adding hysteresis with external resistors in+ thresholds in- v hyst v tl v th hysteresis band out in+ out r l r1 r2 v ref v in v dd v out v dd v ss in- max9093/max9095
