GENERAL DESCRIPTION
The ADG786 and ADG788 are low voltage, CMOS devices
comprising three independently selectable SPDT (single pole,
double throw) switches and four independently selectable SPDT
switches respectively.
Low power consumption and operating supply range of 1.8 V to
5.5 V and dual ± 2.5 V make the ADG786 and ADG788 ideal
for battery powered, portable instruments and many other
applications. All channels exhibit break-before-make switch-
ing action preventing momentary shorting when switching
channels. An EN input on the ADG786 is used to enable or
disable the device. When disabled, all channels are switched OFF.
These multiplexers are designed on an enhanced submicron
process that provides low power dissipation yet gives high switch-
ing speed, very low on resistance, high signal bandwidths and
low leakage currents. On resistance is in the region of a few
ohms, is closely matched between switches and very flat over
the full signal range. These parts can operate equally well in
either direction and have an input signal range which extends to
the supplies.
The ADG786 and ADG788 are available in small 20-lead
chip scale packages.
PRODUCT HIGHLIGHTS
1. Small 20-Lead 4 mm × 4 mm Chip Scale Packages (CSP).
2. Single/Dual Supply Operation. The ADG786 and ADG788
are fully specified and guaranteed with 3 V ± 10% and
5 V ± 10% single supply rails, and ± 2.5 V ± 10% dual
supply rails.
3. Low On Resistance (2.5 Ω typical).
4. Low Power Consumption (<0.01 µW).
5. Guaranteed Break-Before-Make Switching Action.

NOTES
1Stresses above those listed under Absolute Maximum Ratings may cause perma-
nent damage to the device. This is a stress rating only; functional operation of the
device at these or any other conditions above those listed in the operational
sections of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability. Only one absolute
maximum rating may be applied at any one time.
2Overvoltages at A, EN, IN, S, or D will be clamped by internal diodes. Current
should be limited to the maximum ratings given.
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 ADG786/ADG788 features 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.
