general description the max4754/max4755/max4756 low on-resistance, analog switches operate from a single +1.8v to +5.5v supply. the max4754 and max4755 are dual, double- pole, double-throw (dpdt) switches. the max4756 is a quad, single-pole double-throw (spdt) switch. they are configured to route either audio or data signals. the max4754 has four 0.5 ? spdt switches for audio- signal routing and two logic control inputs. the max4755 has four 0.5 ? spdt switches (with two switches that have an additional 11 ? series resistor at the nc terminals). this allows users to drive an 8 ? speaker as a 32 ? load (ear speaker). the max4756 has four 0.5 ? spdt switches controlled by one logic control input and an enable pin ( en ) to disable the switches. the max4754/max4755/max4756 are available in a space-saving 16-pin thin qfn and a tiny 16-bump 2mm x 2mm chip-scale package (ucsp). applications speaker-headset switching audio-signal routing cellular phones pdas/hand-held devices notebook computers features ? data and audio-signal routing ? low r on (0.5 ? ) audio switches ? 0.1 ? channel-to-channel matching ? 0.2 ? on-resistance flatness ? 0.02% thd ? +1.8v to +5.5v supply range ? rail-to-rail signal handling ? 16-bump ucsp (2mm x 2mm) max4754/max4755/max4756 0.5 ? ? , quad spdt switches in ucsp/qfn ________________________________________________________________ maxim integrated products 1 ordering information 19-2942; rev 0; 8/03 for pricing, delivery, and ordering information, please contact maxim/dallas direct! at 1-888-629-4642, or visit maxim? website at www.maxim-ic.com. part temp range pin-package max4754 ebe-t -40? to +85? 16 ucsp-16 max4754ete -40? to +85? 16 thin qfn (4mm x 4mm) max4755 ebe-t* -40? to +85? 16 ucsp-16 MAX4755ETE* -40? to +85? 16 thin qfn (4mm x 4mm) max4756 ebe-t* -40? to +85? 16 ucsp-16 max4756ete* -40? to +85? 16 thin qfn (4mm x 4mm) max4754 ina no1 nc1 no2 nc2 no3 nc3 no4 nc4 inb com3 com4 com1 com2 max4755 ina no1 nc1 no2 nc2 no3 nc3 no4 nc4 inb com3 com4 com1 com2 max4756 no1 ina nc1 no2 nc2 no3 nc3 no4 nc4 com3 com4 com1 com2 11 ? 11 ? en functional diagrams ucsp is a trademark of maxim integrated products, inc. pin configurations appear at end of data sheet. * future product?ontact factory for availability.

max4754/max4755/max4756 detailed description the max4754/max4755/max4756 low on-resistance analog switches operate from a single +1.8v to +5.5v supply. the devices are fully specified for nominal 3v applications. the max4754 dpdt switch has two logic control inputs with each input controlling two spdt switches. each switch has a 0.5 ? on-resistance in the no and nc ter- minals making it ideal for switching audio signals. the max4755 dpdt switch also has four 0.5 ? spdt switches with the switch pairs 1 and 2 adding an 11.5 ? series resistor to the nc terminal. this feature allows the user to drive an 8 ? speaker as a 32 ? load, allowing it to be used as an ear speaker. two logic control inputs are used to control the four switches. the max4756 has four 0.5 ? spdt switches controlled by one logic control input (ina) and en input to disable the switches. applications information digital control inputs the max4754/max4755/max4756 logic inputs accept up to +5.5v regardless of the supply voltage. for example, with a +3.3v supply in_ can be driven low to gnd and high to +5.5v, which allows mixed logic lev- els in a system. driving the control logic inputs rail-to- rail also minimizes power consumption. for a +3v supply voltage, the logic thresholds are 0.5v (low) and 1.4v (high). for the max4756, drive en low to enable the com_. when en is high, com _ is high impedance. analog signal levels analog signal inputs over the full voltage range (0v to v+) are passed through the switch with minimal change in on-resistance (see the typical operating charac- teristics ). the switches are bidirectional so no_, nc_, and com_ can be either inputs or outputs. power-supply bypassing power-supply bypassing improves noise margin and pre- vents switching noise from propagating from the v+ sup- ply to other components. a 0.1? capacitor connected from v+ to gnd is adequate for most applications. ucsp applications information for the latest application details on ucsp construction, dimensions, tape carrier information, printed circuit board techniques, bump-pad layout, and recommend- ed reflow temperature profile, as well as the latest infor- mation on reliability testing results, go to the maxim website at www.maxim-ic.com/ucsp for the application note: ucsp? wafer-level chip-scale package . 0.5 ? ? , quad spdt switches in ucsp/qfn 8 _______________________________________________________________________________________
