GENERAL DESCRIPTION

The ADG787 is a low voltage, CMOS device that contains two
independently selectable, single-pole, double-throw (SPDT)
switches. It is designed as a general analog/digital switch and
can also be used for routing USB 1.1 signals.

This device offers low on resistance of typically 2.5 Ω, making
the part an attractive solution for applications that require low
distortion through the switch.

The ADG787 comes in a tiny 3 × 4 bump, 1.50 mm × 2.00 mm
WLCSP, a tiny 10-lead LFCSP, and a 10-lead MSOP. These
packages make the ADG787 the ideal solution for space­constrained applications.

Each switch conducts equally well in both directions when on
and has an input signal range that extends to the supplies. The
ADG787 exhibits break-before-make switching action.

Overvoltages at IN, S, or D are clamped by internal diodes. Current should be

limited to the maximum ratings given.

Stresses above those listed under Absolute Maximum Ratings
may cause permanent 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.

ESD 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 this product 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.

Charge Injection

A measure of the glitch impulse transferred from the digital

Rise Time Delay
The rise time of a signal is a measure of the time for the signal

time delay is the difference between the rise time, measured at
the input, and the rise time, measured at the output.

Fall Time Delay
The fall time of a signal is a measure of the time for the signal to
fall from 90% of the ON level to 10% of the ON level. Fall time
delay is the difference between the fall time, measured at the
