max9030/max9031/max9032/max9034 low-cost, ultra-small, single/dual/quad single-supply comparators 6 maxim integrated detailed description the max9030/max9031/max9032/max9034 are sin- gle/dual/quad low-cost comparators. they have an operating supply voltage from +2.5v to +5.5v when operating from a single supply and from ?.25v to ?.75v when operating from dual power supplies, and consume only 35?. their common-mode input voltage range extends from the negative supply to within 1.1v of the positive supply. internal hysteresis ensures clean output switching, even with slow-moving input signals. shutdown mode the max9030 comparator comes with a power-saving shutdown mode. when in shutdown, the supply current drops from a typical 35? to 0.05?, and the outputs become high impedance. shdn has a high input imped- ance and typically draws 0.1? when connected to v ss or v dd . a maximum logic low voltage of 0.3v v dd applied to shdn places the device in the shutdown mode. a minimum logic high voltage of 0.7v v dd applied to shdn will enable normal operation. to dis- able shutdown, connect shdn to v dd . applications information adding hysteresis hysteresis extends the comparator? noise margin by increasing the upper threshold and decreasing the lower threshold. a voltage-divider from the output of the comparator sets the trip voltage. therefore, the trip volt- age is related to the output voltage. these comparators have 4mv 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: pin description pin m a x9 0 3 0 m a x9 0 3 1 m a x9 0 3 2 m a x9 0 3 4 name function 1 1 in+ comparator noninverting input 224 1 1v ss n eg ati ve s up p l y v ol tag e. byp ass w i th a 0.1? cap aci tor . 3 3 in- comparator inverting input 4 4 out comparator output 5 shdn shutdown 658 4 v dd p osi ti ve s up p l y v ol tag e. byp ass w i th a 0.1? cap aci tor . 1 1 outa comparator a output 2 2 ina- comparator a inverting input 3 3 ina+ comparator a noninverting input 5 5 inb+ comparator b noninverting input 6 6 inb- comparator b inverting input 7 7 outb comparator b output 8 outc comparator c output 9 inc- comparator c inverting input 10 inc+ comparator c noninverting input 12 ind+ comparator d noninverting input 13 ind- comparator d inverting input 14 outd comparator d output
