www.austriamicrosystems.com/analog-switches/as1747-50 revision 1.02 10 - 16 as1747, as1748, as1749, as1750 datasheet - detailed description 8 detailed description the as1747? as1750 are operating from a +1.8v to +5.5v supply and feature a negative signal capability that allows signals below ground to pass through without distortion. a break-before-make switching and a low on-resistance are also included in this analog dual spdt switches. the device is fully specified for a 3.0v application. a headphone or mute detection is included in the as1748 and as1750. this function is realized with a comparator which has an internally generated thresh-hold of about 1/3 of v cc . to reduce click-and-pop sounds when switching between precharged points the as1749 and as1750 have an internal shunt switch. this shunt switch automatically discharges any capacitance at the no and nc connection points. 9 application information digital control inputs the logic inputs of the as1747? as1750 accept up to +5.5v independent of the supply voltage. due to this a mixing of the logic levels in a system is possible. for example, with a +3.3v supply, in_ can be driven low to gnd and high to +5.5v. for a +1.8v supply voltage, the logic levels are 0.5v (low) and 1.4v (high); for a +5v supply voltage, the logic levels are 0.8v (low) and 2.0v (high). analog signal levels the change of the on-resistance of the as1747? as1750 is very little for analog input signals over the whole supply voltage range. the switches are bi-directional, so the no_, nc_, and com_ pins can be either inputs or outputs. the as1747? as1750 pass signals as low as v cc - 5.5v, including signals below ground with minimal distortion. comparator (as1748 1 /as1750) to implement a mute and headphone function, a comparator is included in the as1748 and as1750. the negative ter- minal of this comparator is connected to the outside (via pin cmp-) while the positive terminal is internally set to v cc /3. the output of the comparator (cmpo) is logic high when th e negative terminal (cmp-) is below the threshold. cmpo is logic low when cmp- is higher than v cc /3. headphone audio signals are typical biased to v cc /2 so a comparator threshold of v cc /3 is sufficient for the head- phone detection. shunt switch (as1749 1 /as1750) due to the switching between audio sources, audible click-and-pop sounds occur. to reduce this sounds a 100 shunt switch is implemented in the as1749 and as1750. this shunt switch automatically discharges any capacitance at the nc_ or no_ terminals when they are unconnected to com_. audible clicks and pops are caused when a step dc voltage is switched into the speaker. by automatically discharging the side that is not conne cted, any residual dc volt age is removed, thereby reducing the clicks and pops. power-supply sequencing and overvoltage protection caution: stresses beyond the listed absolute maximum ratings in table 3 on page 4 may cause permanent damage to the device. exposure to absolute maximum rating conditions for extended periods may affect device reliability. proper power-supply sequencing is recommended for all cmos devices. always apply v cc before applying analog signals, especially if the analog signal is not current-limited. 1. on request ams ag technical content still valid
