GENERAL DESCRIPTION
The ADG701/ADG702 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 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.

PRODUCT HIGHLIGHTS
1. 1.8 V to 5.5 V Single-Supply Operation.
The ADG701/ADG702 offer high performance, including
low on resistance and fast switching times, and are fully
specified and guaranteed with 3 V and 5 V supply rails.
2. Very Low RON (3 Ω Maximum at 5 V, 5 Ω Maximum at 3 V).
At 1.8 V operation, RON is typically 40 Ω over the tempera-
ture range.
3. On Resistance Flatness RFLAT(ON) (1 Ω Maximum).
4. −3 dB Bandwidth > 200 MHz.
5. Low Power Dissipation.
CMOS construction ensures low power dissipation.
6. Fast tON/tOFF.
