GENERAL DESCRIPTION
The ADG711, ADG712, and ADG713 are monolithic CMOS
devices containing four independently selectable switches. These
switches are designed on an advanced submicron process that
provides low power dissipation yet gives high switching speed, low
on resistance, low leakage currents, and high bandwidth.
The ADG711/ADG712/ADG713 are available in 16-lead TSSOP
and 16-lead SOIC packages.
PRODUCT HIGHLIGHTS
The ADG711, ADG712, and ADG713 contain four independent
single-pole/single-throw (SPST) switches. The ADG711 and
ADG712 differ only in that the digital control logic is inverted. The
ADG711 switches are turned on with a logic low on the appropriate
control input, while a logic high is required to turn on the switches
of the ADG712. The ADG713 contains two switches whose digital
control logic is similar to the ADG711, while the logic is inverted
on the other two switches.
1.8 V to 5.5 V Single-Supply Operation.
The ADG711, ADG712, and ADG713 offer high performance
and are fully specified and guaranteed with 3 V and 5 V
supply rails.
2.
Very Low RON (4.5 Ω maximum at 5 V, 8 Ω maximum at 3 V).
At supply voltage of 1.8 V, RON is typically 35 Ω over the
temperature range.
3.
Low On Resistance Flatness.
4.
−3 dB Bandwidth >200 MHz.
5.
Low Power Dissipation. CMOS construction ensures low
power dissipation.
6.
Fast tON/tOFF.
7.
Break-Before-Make Switching.
This prevents channel shorting when the switches are
configured as a multiplexer (ADG713 only).
8.
They are designed to operate from a single 1.8 V to 5.5 V supply,
making them ideal for use in battery-powered instruments and
with the new generation of DACs and ADCs from Analog Devices,
Inc. Fast switching times and high bandwidth make the parts
suitable for switching USB 1.1 data signals and video signals.
1.
16-Lead TSSOP and 16-Lead SOIC Packages.
Each switch conducts equally well in both directions when On. The
ADG713 exhibits break-before-make switching action.
