adg719 rev. d | page 12 of 16 applications information the adg719 belongs to analog devices new family of cmos switches. this series of general-purpose switches has improved switching times, lower on resistance, higher bandwidths, low power consumption, and low leakage currents. adg719 supply voltages functionality of the adg719 extends from 1.8 v to 5.5 v single supply, which makes it ideal for battery-powered instruments where power efficiency and performance are important design parameters. it is important to note that the supply voltage effects the input signal range, the on resistance, and the switching times of the part. by taking a look at the typical performance characteristics and the specifications, the effects of the power supplies can be clearly seen. for v dd = 1.8 v operation, r on is typically 40 over the temperature range. on response vs. frequency figure 22 illustrates the parasitic components that affect the ac performance of cmos switches (the switch is shown surrounded by a box). additional external capacitances will further degrade some performance. these capacitances affect feedthrough, crosstalk, and system bandwidth. s c d d v out r load c load v in r on c ds 08708-022 figure 22. switch represented by equivalent parasitic components the transfer function that describes the equivalent diagram of the switch ( figure 22 ) is of the form a(s) shown below: ? ? ? ? ? ? ? ? + + = 1) ( 1)( )( t on t dson t crrs crs rsa where: r t = r load /(r load + r on ) c t = c load + c d + c ds the signal transfer characteristic is dependent on the switch channel capacitance, c ds . this capacitance creates a frequency zero in the numerator of the transfer function a(s) . because the switch on resistance is small, this zero usually occurs at high frequencies. the bandwidth is a function of the switch output capacitance combined with c ds and the load capacitance. the frequency pole corresponding to these capacitances appears in the denominator of a(s) . the dominant effect of the output capacitance, c d , causes the pole breakpoint frequency to occur first. therefore, in order to maximize bandwidth, a switch must have a low input and output capacitance and low on resistance. the on response vs. frequency plot for the adg719 can be seen in figure 12 . off isolation off isolation is a measure of the input signal coupled through an off switch to the switch output. the capacitance, c ds , couples the input signal to the output load when the switch is off, as shown in figure 23 . s c d d v out r load c load v in c ds 08708-023 figure 23. off isolation is affected by external load resistance and capacitance the larger the value of c ds , the larger the values of feedthrough that will be produced. figure 10 illustrates the drop in off isolation as a function of frequency. from dc to roughly 200 khz, the switch shows better than ?95 db isolation. up to frequencies of 10 mhz, the off isolation remains better than ?67 db. as the frequency increases, more and more of the input signal is coupled through to the output. off isolation can be maximized by choosing a switch with the smallest c ds possible. the values of load resistance and capacitance also affect off isolation, since they contribute to the coefficients of the poles and zeros in the transfer function of the switch when open. ? ? ? ? ? ? ? ? +++ = 1) ()( ) ( )( ds d load load ds load cccrs crs sa
