These switches are designed on an advanced submicron process that provides low power dissipation yet high switching speed, low on resistance, and low leakage currents. In addition, −3 dB bandwidths of greater than 200 MHz can be achieved. The ADG701/ADG702 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, Inc. Figure 1 shows that with a logic input of 1, the switch of the ADG701 is closed and that of the ADG702 is open. Each switch conducts equally well in both directions when on. The ADG701/ADG702 are available in 5-lead SOT-23, 6-lead SOT-23, and 8-lead MSOP packages.
