Description
The CDG701/CDG702 are monolithic CMOS SPST switches. 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 CDG701/CDG702 can operate from a single 1.8 V to 5.5 V supply, making it ideal for use in battery-powered instruments.Figure 1 shows that with a logic input of 1, the switch of the CDG701 is closed and that of the CDG702 is open. Each switch conducts equally well in both directions when on. The CDG701/CDG702 are available in 5-lead SOT-23, 6-lead SOT-23, and 8-lead MSOP packages.
