GENERAL DESCRIPTION
PRODUCT HIGHLIGHTS
1. 20-Lead 4 mm ϫ 4 mm Chip Scale Package (CSP).
The ADG781, ADG782, and ADG783 are monolithic CMOS
devices containing four independently selectable switches. These
switches are designed on an advanced submicron process that
provides low power dissipation and high switching speed, low on
resistance, low leakage currents and high bandwidth.
2. 1.8 V to 5.5 V Single Supply Operation. The ADG781,
ADG782, and ADG783 offer high performance and are
fully specified and guaranteed with 3 V and 5 V supply
rails.
They are designed to operate from a single 1.8 V to 5.5 V sup-
ply, making them ideal for use in battery powered instruments
and with the new generation of DACs and ADCs from Analog
Devices. Fast switching times and high bandwidth make the
part suitable for video signal switching.
3. Very Low RON (4.5 Ω max at 5 V, 8 Ω max at 3 V). At supply
voltage of 1.8 V, RON is typically 35 Ω over the temperature
range.
4. Low On-Resistance Flatness.
5. –3 dB Bandwidth >200 MHz.
The ADG781, ADG782, and ADG783 contain four independent
single-pole/single throw (SPST) switches. The ADG781 and
ADG782 differ only in that the digital control logic is inverted.
The ADG781 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 ADG782. The ADG783 contains two
switches whose digital control logic is similar to the ADG781,
while the logic is inverted on the other two switches.
6. Low Power Dissipation. CMOS construction ensures low
power dissipation.
7. Fast tON/tOFF.
8. Break-Before-Make Switching. This prevents channel shorting
when the switches are configured as a multiplexer (ADG783
only).
Each switch conducts equally well in both directions when ON.
The ADG783 exhibits break-before-make switching action.
The ADG781/ADG782/ADG783 are available in 20-lead chip
scale packages.

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection.
Although the ADG781/ADG782/ADG783 feature proprietary ESD protection circuitry, permanent
damage may occur on devices subjected to high-energy electrostatic discharges. Therefore, proper
ESD precautions are recommended to avoid performance degradation or loss of functionality.

With the resistor values shown in the circuit, and using different
combinations of the switches, gain in the range of 2 to 16 can
be achieved.
