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, low leakage currents and –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 instru-
ments and with the new generation of DACs and ADCs from
Analog Devices.
As can be seen from the Functional Block Diagrams, with a
logic input of “1” the switch of the ADG701 is closed, while
that of the ADG702 is open. Each switch conducts equally well
in both directions when ON.
The ADG701/ADG702 are available in 6-lead SOT-23 and
8-lead µSOIC 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 is fully specified and guaranteed
with +3 V and +5 V supply rails.
2. Very Low RON (3 max at 5 V, 5 max at 3 V). At 1.8 V
operation, RON is typically 40 over the temperature range.
3. On-Resistance Flatness RFLAT(ON) (1 max).
4. –3 dB Bandwidth >200 MHz.
5. Low Power Dissipation. CMOS construction ensures low
power dissipation.
6. Fast tON/tOFF.
7. Tiny 6-Lead SOT-23 and 8-Lead µSOIC.
