GENERAL DESCRIPTION PRODUCT HIGHLIGHTS The ADG701L/ADG702L are monolithic CMOS SPST switches. These switches are designed using an advanced submicron process that provides low power dissipation, yet offers high switching speed, low on resistance, and low leakage currents. In addition, -3 dB bandwidths of greater than 200 MHz can be achieved. 1. 1.8 V to 5.5 V single-supply operation. The ADG701L/ ADG702L offer high performance, including low on resistance and fast switching times. The ADG701L/ ADG702L are fully specified and guaranteed with 3 V and 5 V supply rails. 2. Very low RON (3 maximum at 5 V, 5 maximum at 3 V). At 1.8 V operation, RON is typically 40 over the temperature range. 3. On resistance flatness RFLAT(ON) (1 maximum). 4. -3 dB bandwidth > 200 MHz. 5. Low power dissipation. CMOS construction ensures low power dissipation. 6. Fast tON/tOFF. The ADG701L/ADG702L can operate from a single 1.8 V to 5.5 V supply, making it ideal for use in battery-powered instruments and with the new generation of DACs and ADCs from Analog Devices. Figure 1 and Figure 2 show that with a logic input of 1, the switch of the ADG701L is closed, while that of the ADG702L is open. Each switch conducts equally well in both directions when on. The ADG701L/ADG702L are packaged as 5-lead SOT-23, 6-lead SOT-23, and 8-lead MSOP. Rev. 0 Information furnished by Analog Devices is believed to be accurate and reliable.

This series of general-purpose switches have improved switching times, lower on resistance, higher bandwidth, low power consumption, and low leakage currents. SUPPLY VOLTAGES Functionality of the ADG701L/ADG702L extends from 1.8 V to 5.5 V single supply, making the parts ideal for battery-powered instruments where power, efficiency, and performance are important design parameters. 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 effects of the power supplies can be clearly seen in the Typical Performance Characteristics and the Specifications sections. The signal transfer characteristic is dependent on the switch channel capacitance, CDS. 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 CDS 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, CD, causes the pole breakpoint frequency to occur first. In order to maximize bandwidth, a switch must have a low input and output capacitance and low on resistance. The on response versus frequency for the ADG701L/ADG702L is shown in Figure 11. OFF ISOLATION Off isolation is a measure of the input signal coupled through an off switch to the switch output. The capacitance, CDS, couples the input signal to the output load when the switch is off (see Figure 20). BANDWIDTH Figure 19 illustrates the parasitic components that affect the ac performance of CMOS switches (a box surrounds the switch). Additional external capacitances further degrade some performance. These capacitances affect feedthrough, crosstalk, and system bandwidth. CDS S VOUT VIN CD CLOAD RLOAD Figure 20. Off Isolation Is Affected by External Load Resistance and Capacitance CDS S D VOUT CD CLOAD RLOAD 05486-018 RON VIN D 05486-019 For VDD = 1.8 V operation, RON is typically 40 over the temperature range. Figure 19. Switch Represented by Equivalent Parasitic Components The transfer function that describes the equivalent diagram of the switch (see Figure 19) is of the form A(s), as shown in the following equation: s(RON C DS ) + 1 A(s) = RT s(RON CT RT ) + 1 The larger the value of CDS, the larger the values of feedthrough produced. Figure 10 illustrates the drop in off isolation as a function of frequency. From dc to roughly 1 MHz, the switch shows better than -75 dB isolation. Up to frequencies of 10 MHz, the off isolation remains better than -55 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 CDS possible. The values of load resistance and capacitance also affect off isolation, as they contribute to the coefficients of the poles and zeros in the transfer function of the switch when open. where CT = CLOAD + CD + CDS. s(RLOADC DS ) + 1 A(s) = RT s(RLOAD )(CT ) + 1 Rev. 0 | Page 10 of 12 ADG701L/ADG702L OUTLINE DIMENSIONS 2.90 BSC 3.00 BSC 8 3.00 BSC 1 6 5 4 1 2 3 2.80 BSC 1.60 BSC 5 4.90 BSC PIN 1 INDICATOR 4 0.95 BSC PIN 1 1.90 BSC 1.30 1.15 0.90 0.65 BSC 1.10 MAX 0.15 0.00 0.38 0.22 COPLANARITY 0.10 0.23 0.08 1.45 MAX 0.80 0.60 0.40 8 0 0.50 0.30 0.15 MAX SEATING PLANE SEATING PLANE 0.22 0.08 10 4 0 0.60 0.45 0.30 COMPLIANT TO JEDEC STANDARDS MO-187-AA COMPLIANT TO JEDEC STANDARDS MO-178-AB Figure 21. 8-Lead Mini Small Outline Package [MSOP] (RM-8) Dimensions shown in millimeters Figure 22. 6-Lead Small Outline Transistor Package [SOT-23] (RT-6) Dimensions shown in millimeters 2.90 BSC 5 4 2.80 BSC 1.60 BSC 1 2 3 PIN 1 0.95 BSC 1.90 BSC 1.30 1.15 0.90 1.45 MAX 0.15 MAX 0.50 0.30 0.22 0.08 SEATING PLANE 10 5 0 COMPLIANT TO JEDEC STANDARDS MO-178-AA Figure 23. 5-Lead Small Outline Transistor Package [SOT-23] (RJ-5) Dimensions shown in millimeters Rev. 0 | Page 11 of 12 0.60 0.45 0.30 ADG701L/ADG702L ORDERING GUIDE Model ADG701LBRJ-500RL7 ADG701LBRJ-REEL ADG701LBRJ-REEL7 ADG701LBRJZ-500RL7 2 ADG701LBRJZ-REEL2 ADG701LBRJZ-REEL72 ADG701LBRM ADG701LBRM-REEL ADG701LBRM-REEL7 ADG701LBRMZ2 ADG701LBRMZ-REEL2 ADG701LBRMZ-REEL72 ADG701LBRT-REEL ADG701LBRT-REEL7 ADG701LBRTZ-REEL2 ADG701LBRTZ-REEL72 ADG702LBRJ-REEL ADG702LBRJ-REEL7 ADG702LBRJZ-500RL72 ADG702LBRJZ-REEL2 ADG702LBRJZ-REEL72 ADG702LBRM ADG702LBRM-REEL ADG702LBRM-REEL7 ADG702LBRMZ2 ADG702LBRMZ-REEL2 ADG702LBRMZ-REEL72 ADG702LBRT-REEL ADG702LBRT-REEL7 ADG702LBRTZ-REEL2 ADG702LBRTZ-REEL72 1 2 Temperature Range -40C to +85C -40C to +85C -40C to +85C -40C to +85C -40C to +85C -40C to +85C -40C to +85C -40C to +85C -40C to +85C -40C to +85C -40C to +85C -40C to +85C -40C to +85C -40C to +85C -40C to +85C -40C to +85C -40C to +85C -40C to +85C -40C to +85C -40C to +85C -40C to +85C -40C to +85C -40C to +85C -40C to +85C -40C to +85C -40C to +85C -40C to +85C -40C to +85C -40C to +85C -40C to +85C -40C to +85C Package Description 5-Lead Small Outline Transistor Package [SOT-23] 5-Lead Small Outline Transistor Package [SOT-23] 5-Lead Small Outline Transistor Package [SOT-23] 5-Lead Small Outline Transistor Package [SOT-23] 5-Lead Small Outline Transistor Package [SOT-23] 5-Lead Small Outline Transistor Package [SOT-23] 8-Lead Mini Small Outline Package [MSOP] 8-Lead Mini Small Outline Package [MSOP] 8-Lead Mini Small Outline Package [MSOP] 8-Lead Mini Small Outline Package [MSOP] 8-Lead Mini Small Outline Package [MSOP] 8-Lead Mini Small Outline Package [MSOP] 6-Lead Small Outline Transistor Package [SOT-23] 6-Lead Small Outline Transistor Package [SOT-23] 6-Lead Small Outline Transistor Package [SOT-23] 6-Lead Small Outline Transistor Package [SOT-23] 5-Lead Small Outline Transistor Package [SOT-23] 5-Lead Small Outline Transistor Package [SOT-23] 5-Lead Small Outline Transistor Package [SOT-23] 5-Lead Small Outline Transistor Package [SOT-23] 5-Lead Small Outline Transistor Package [SOT-23] 8-Lead Mini Small Outline Package [MSOP] 8-Lead Mini Small Outline Package [MSOP] 8-Lead Mini Small Outline Package [MSOP] 8-Lead Mini Small Outline Package [MSOP] 8-Lead Mini Small Outline Package [MSOP] 8-Lead Mini Small Outline Package [MSOP] 6-Lead Small Outline Transistor Package [SOT-23] 6-Lead Small Outline Transistor Package [SOT-23] 6-Lead Small Outline Transistor Package [SOT-23] 6-Lead Small Outline Transistor Package [SOT-23] Due to package size limitations, these three characters represent the part number.
