GENERAL DESCRIPTION

These parts can operate equally well as either multiplexers or

demultiplexers and have an input signal range that extends to the

supplies. In the OFF condition, signal levels up to the supplies

are blocked. All channels exhibit break-before-make switching

action, preventing momentary shorting when switching channels.

The ADG731/ADG725 are monolithic, CMOS, 32-channel/

dual 16-channel analog multiplexers with a serially controlled

3-wire interface. The ADG731 switches one of 32 inputs

(S1–S32) to a common output, D. The ADG725 can be config-

ured as a dual mux switching one of 16 inputs to one output, or a

differential mux switching one of 16 inputs to a differential output.

The ADG731 and ADG725 are serially controlled 32-channel,

and dual/differential 16-channel multiplexers, respectively. They

are available in either a 48-lead LFCSP or TQFP package.

These mulitplexers utilize a 3-wire serial interface that is com-

patible with SPI^®, QSPI^™, MICROWIRE^™, and some DSP

interface standards. On power-up, the Internal Shift Register

contains all zeros and all switches are in the OFF state.

PRODUCT HIGHLIGHTS

1. 3-Wire Serial Interface.

These multiplexers are designed on an enhanced submicron

process that provides low power dissipation yet gives high switch-

ing speed with very low on resistance and leakage currents.

They operate from a single supply of 1.8 V to 5.5 V or a

±2.5 V dual supply, making them ideally suited to a variety of

applications. On resistance is in the region of a few ohms, is

closely matched between switches, and is very flat over the full

signal range.

2. 1.8 V to 5.5 V Single-Supply or ±2.5 V Dual-Supply

Operation. These parts are specified and guaranteed

with 5 V ±10%, 3 V ±10% single-supply,

and ±2.5 V ±10% dual-supply rails.

3. On Resistance of 4 W.

4. Guaranteed Break-Before-Make Switching Action.

5. 7 mm ¥ 7 mm 48-Lead Chip Scale Package (LFCSP) or

48-Lead TQFP Package.
