general description the max9060?ax9064 are small single comparators, ideal for a wide variety of portable electronics applica- tions such as cell phones, media players, and notebooks that have extremely tight board space and power con- straints. these comparators are offered in both, a minia- ture 4-bump ucsp package with a 1mm x 1mm footprint (as small as two 0402 resistors), and a 5-pin sot23 package. the max9060?ax9064 feature an input voltage range of -0.3v to +5.5v independent of supply voltage. these devices maintain high impedance at the inputs even when powered down (v cc or v ref = 0v). they also feature internal filtering to provide high rf immunity. the max9060 and max9061 have open-drain outputs and draw quiescent supply current from a user-supplied reference voltage, v ref , between 0.9v and 5.5v. these devices consume only 100na (max) supply current and operate over the extended -40? to +85? temperature range. the max9062, max9063 and max9064 are single com- parators with an internal 0.2v reference. these devices feature either a push-pull or an open-drain output. they consume only 700na (max) supply current. the max9062, max9063, and max9064 operate down to v cc = 1v over the extended -40? to +85? temperature range. applications cell phones portable media players electronic toys notebook computers portable medical devices features tiny 1mm x 1mm x 0.6mm 4-bump ucsp footprint = two 0402 resistors also available in a 5-pin sot23 package ultra-low operating current (100na max) input voltage range = -0.3v to +5.5v external ref range = 0.9v to 5.5v (max9060/max9061) internal ref voltage = 0.2v (max9062/max9063/max9064) 15? propagation delay -40? to +85? extended temperature range max9060?ax9064 ultra-small, low-power single comparators in 4-bump ucsp and 5 sot23 ________________________________________________________________ maxim integrated products 1 max9060?ax9064 max9060 max9064 a1 ucsp sot23 ref = max9060/max9061 (v cc ) = max9062?ax9064 top view (bumps on bottom) a2 b1 b2 in gnd out ref (v cc ) 1 + 3 2 5 4 ref (v cc ) gnd out in gnd pin configuration 19-4105; rev 4; 3/11 for pricing, delivery, and ordering information, please contact maxim direct at 1-888-629-4642, or visit maxim? website at www.maxim-ic.com. evaluation kit available ordering information part pin-package top mark max9060 ebs+g45 4 ucsp afx max9060euk+ 5 sot23 affg max9061 ebs+g45 4 ucsp afy max9061euk+ 5 sot23 affh max9062 ebs+g45 4 ucsp afz max9062euk+ 5 sot23 affi max9063 ebs+g45 4 ucsp aga max9063euk+ 5 sot23 affj max9064 ebs+g45 4 ucsp agb max9064euk+ 5 sot23 affk note: all devices are specified over the extended -40? to +85? operating temperature range. + denotes a lead(pb)-free/rohs-compliant package. g45 = protective die coating. ucsp is a trademark of maxim integrated products, inc. selector guide and typical operating circuits appear at end of data sheet.

max9060?ax9064 ultra-small, low-power single comparators in 4-bump ucsp and 5 sot23 _______________________________________________________________________________________ 7 detailed description the max9060?ax9064 are extremely small com- parators ideal for compact, low-current, and low- voltage applications. the max9060/max9061 consume only 50na (typ) oper- ating current, while the max9062/max9063/max9064 consume only 400na (typ). the low-voltage operating capability of the max9060?ax9064 makes these devices extremely attractive to long-life battery-operat- ed devices?hese applications can now use a single digital power-supply rail to power the new generation of microcontrollers (which can be down to 0.9v). a single aa/aaa cell can drop down to 0.9v in full discharge. all parts are available in a tiny 4-bump ucsp, that is only 0.6mm tall, and occupies a 1mm x 1mm footprint and a 5-pin sot23. input stage circuitry noninverting inputs are available on the max9060/ max9062/max9064 and inverting inputs are available on the max9061/max9063. the max9060?ax9064 incorporate an innovative input stage architecture that allows their input voltage to exceed v cc by several volts (limited only by the absolute maximum ratings ). this is unlike traditional comparators that have an input esd diode clamp between the input and v cc , limiting this maximum over- voltage to about 0.3v. the max9060?ax9064 archi- tecture maintains a high input impedance to input signals even when the device power-supply voltage is completely turned off (v cc or ref taken to 0v). this greatly benefits flexible power-saving schemes to be easily implemented in advanced battery-operated devices. on-chip filtering provides immunity from any rf noise being picked up by input traces. these devices feature an internal temperature-compensated, low-power 0.2v reference voltage. output stage structure the max9060?ax9063 have open-drain outputs that allow them to interface to logic circuitry running from supply voltages other than the one supplied to the part. these devices require an external pullup resistor or current source for proper operation. many microcon- troller digital inputs ports can be readily programmed to include these. the max9064 has a push-pull output stage that can both sink and source current, eliminating the need for an external pullup resistor. in this case, the max9064 uses the microcontroller? power supply as v cc . pin/bump description bump pin ucsp sot23 max9060 max9061 max9062 max9063 max9064 max9060 max9061 max9062 max9063 max9064 name function a1 a1 5 5 out comparator output. the max9060?ax9063 have open-drain outputs. the max9064 has a push-pull output. a2 a2 4 4 in comparator input. the max9060, max9062, and max9064 have noninverting inputs. the max9061 and max9063 have inverting inputs. ?1 1v cc power-supply voltage. bypass to ground with a 0.1? bypass capacitor. b1 1 ref external reference input. ref also supplies power to the device. bypass to ground with a 0.1? bypass capacitor. b2 b2 2, 3 2, 3 gnd ground.
max9060?ax9064 ultra-small, low-power single comparators in 4-bump ucsp and 5 sot23 8 _______________________________________________________________________________________ applications information bypassing ref/v cc place a 0.1? capacitor between ref or v cc and gnd as close as possible to the device. during a switching event, all comparators draw a current spike from their power-supply rails. this current spike is minimized by the use of an internal break-before-make design. hysteresis operation the max9060?ax9064 feature internal hysteresis for noise immunity and glitch-free operation. if additional hysteresis is needed, an external positive feedback net- work can be easily implemented on the max9060, max9062, and max9064 noninverting input devices. additional external hysteresis is not recommended for the max9061 due to possible crossover current-related noise problems. additional external hysteresis is not possible on the max9063 because the noninverting input of the comparator is not externally accessible. adaptive signal level detector the max9060 and max9061 can be used as an adap- tive signal-level detector. feed a dac output voltage to ref and connect the input to a variable signal level. as the dac output voltage is varied from 0.9v to 5.5v, a corresponding signal level threshold-detector circuit is implemented. see figure 1. part input voltage conditions action at output v in > v ref external pullup resistor pulls output high. max9060 v in < v ref output asserts low. v in > v ref output asserts low. max9061 v in < v ref external pullup resistor pulls output high. v in > 0.2v external pullup resistor pulls output high. max9062 v in < 0.2v output asserts low. v in > 0.2v output asserts low. max9063 v in < 0.2v external pullup resistor pulls output high. v in > 0.2v output asserts high. max9064 v in < 0.2v output asserts low. figure 1. adaptive signal level detector max9060 dac ref in microcontroller internal pullup v dd i/o out table 1. how devices behave under various input voltage conditions
