GENERAL DESCRIPTION

The ADG5433 and ADG5434 are monolithic industrial CMOS

analog switches comprising three independently selectable

single-pole, double-throw (SPDT) switches and four indepen-

dently selectable SPDT switches, respectively.

All channels exhibit break-before-make switching action that

prevents momentary shorting when switching channels. An EN

input on the ADG5433 (LFCSP and TSSOP packages) is used to

enable or disable the device. When disabled, all channels are

switched off.

The ultralow on resistance and on-resistance flatness of these

switches make them ideal solutions for data acquisition and gain

switching applications, where low distortion is critical.

PRODUCT HIGHLIGHTS

High Voltage Latch-Up Proof,

Trench isolation guards against latch-up. A dielectric trench

separates the P and N channel transistors thereby preventing

latch-up even under severe overvoltage conditions.

Low R

Dual-supply operation. For applications where the analog

signal is bipolar, the ADG5433/ADG5434 can be operated

from dual supplies up to ±22 V.

Single-supply operation. For applications where the analog

signal is unipolar, the ADG5433/ADG5434 can be operated

from a single-rail power supply up to 40 V.
