GENERAL DESCRIPTION

The ADG733 and ADG734 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 ADG733 and ADG734 ideal for

battery powered, portable instruments. All channels exhibit

break-before-make switching action preventing momentary

shorting when switching channels. An EN input on the ADG733 is

used to enable or disable the device. When disabled, all channels

are switched OFF.

These 2–1 multiplexers/SPDT switches are designed on an

enhanced submicron process that provides low power dissipation

yet gives high switching 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 is

very flat over the full signal range. These parts can operate equally

well in either direction and have an input signal range that extends

to the supplies.

The ADG733 is available in small TSSOP and QSOP packages,

while the ADG734 is available in a small TSSOP package.

... 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 ADG733/ADG734 feature proprietary ESD protection circuitry, permanent dam- age may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality ...
