PRODUCT HIGHLIGHTS
GENERAL DESCRIPTION
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.
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.
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
temperature range.
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.
3. On resistance flatness RFLAT(ON) (1 Ω maximum).
4. −3 dB bandwidth > 200 MHz.
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.
5. Low power dissipation. CMOS construction ensures low
power dissipation.
6. Fast tON/tOFF
.
The ADG701L/ADG702L are packaged as 5-lead SOT-23,
6-lead SOT-23, and 8-lead MSOP.
