Figure 2. IN2 AG723 WITCHE HOWN FOR A LOGIC "0" INPUT Figure 3. IN IN GENERAL ECRIPTION The AG72, AG722, and AG723 are monolithic CMO PT switches. These switches are designed on an advanced submicron process that provides low power dissipation yet gives high switching speed, low on resistance, and low leakage currents. The devices are packaged in both a tiny 3 mm 2 mm LFCP and an MOP, making them ideal for space-constrained applications. The AG72, AG722, and AG723 are designed to operate from a single.8 V to 5.5 V supply, making them ideal for use in battery-powered instruments and with the new generation of ACs and ACs from Analog evices, Inc. The AG72, AG722, and AG723 contain two independent single-pole/single-throw (PT) switches. The AG72 and AG722 differ only in that both switches are normally open and normally closed, respectively. In the AG723, witch is normally open and witch 2 is normally closed. Each switch of the AG72, AG722, and AG723 conducts equally well in both directions when on. The AG723 exhibits break-before-make switching action. PROUCT HIGHLIGHT..8 V to 5.5 V single-supply operation. 2. Very low RON (4 Ω max at 5 V, 0 Ω max at 3 V). 3. Low on resistance flatness db bandwidth >200 MHz. 5. Low power dissipation. CMO construction ensures low power dissipation lead MOP and 3 mm 2 mm LFCP. Rev.

12 AG72/AG722/AG723 APPLICATION The AG72/AG722/AG723 belong to a new family of Analog evices CMO switches. This series of general-purpose switches has improved switching times, lower on resistance, higher bandwidths, low power consumption, and low leakage currents. AG72/AG722/AG723 UPPLY VOLTAGE Functionality of the AG72/AG722/AG723 extends from a.8 V to a 5.5 V single supply, which makes it ideal for batterypowered instruments, where important design parameters are power efficiency and performance. It is important to note that the supply voltage affects the input signal range, the on resistance, and the switching times of the part. The typical performance characteristics and the specifications clearly show the effects of the power supplies. For V =.8 V, on resistance is typically 40 Ω over the temperature range. ON REPONE V. FREQUENCY Figure 2 illustrates the parasitic components that affect the ac performance of CMO switches (the switch is shown surrounded by a box). Additional external capacitances further degrade some aspects of performance. These capacitances affect feedthrough, crosstalk, and system bandwidth. C R ON C C LOA R LOA Figure 2. witch Represented by Equivalent Parasitic Components The transfer function that describes the equivalent diagram of the switch (Figure 2) is of the form (A)s, as shown in the following equation: where: A ( s) = R T s CT = CLOA + C + C RT = RLOA/(RLOA + RON) s( R ) + ( ) ON C RON CT RT ata heet The signal transfer characteristic is dependent on the switch channel capacitance, C. 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 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, 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 (see Figure ). OFF IOLATION Off isolation is a measure of the input signal coupled through an off switch to the switch output. The capacitance, C, couples the input signal to the output load, when the switch is off, as shown in Figure 22. C C C LOA RLOA Figure 22. Off Isolation Is Affected by External Load Resistance and Capacitance The larger the value of C, the larger the value of feedthrough produced. Figure 9 illustrates the drop in off isolation as a function of frequency. From dc to roughly MHz, the switch shows better than 80 db isolation. Up to frequencies of 0 MHz, the off isolation remains better than 60 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 possible. The values of load resistance and capacitance also affect off isolation because they contribute to the coefficients of the poles and zeros in the transfer function of the switch when open.
