GENERAL DESCRIPTION

and have an input signal range which extends to the sup-

plies. 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 ADG725/ADG731 are monolithic CMOS 32

channel/dual 16 channel analog multiplexers with a

serially controlled 3-wire interface. The ADG732 switches

one of thirty-two inputs (S1-S32) to a common output, D.

The ADG725 can be configured as a dual mux switching

one of sixteen inputs to one output or a differential mux

switching one of sixteen inputs to a differential output.

They are available in either 48 lead CSP or TQFP

package.

These mulitplexers utilize a 3-wire serial interface that is

compatible with SPI^TM, QSPI^TM, MICROWIRE^TMand

some DSP interface standards. On power-up, the internal

shift register contains all zeros and all switch are in the

OFF state.

PRODUCT HIGHLIGHTS

1. 3-Wire Serial Interface.

2. +1.8 V to +5.5 V Single or 2.5 V Dual Supply

operation. These parts are specified and guaranteed

with +5 V 1ꢀ0, +3 V 1ꢀ0 single supply and

2.5 V 1ꢀ0 dual supply rails.

These multiplexers are designed on an enhanced submi-

cron process that provides low power dissipation yet gives

high switching speed, very low on resistance and leakage

currents. They operate from single supply of 1.8V to 5.5V

and 2.5 V dual supply, making them ideally suited to a

variety of applications. On resistance is in the region of a

few Ohms and is closely matched between switches and

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

equally well as either Multiplexers or De-Multiplexers

3. On Resistance of 4 Ω.

4. Guaranteed Break-Before-Make Switching Action.

5. 7mm x 7mm 48 lead Chip Scale Package (CSP)

or 48 lead TQFP package.
