GENERAL DESCRIPTION

PRODUCT HIGHLIGHTS

The ADG738 and ADG739 are CMOS analog matrix switches

with a serially-controlled 3-wire interface. The ADG738 is an

8-channel matrix switch, while the ADG739 is a dual 4-channel

matrix switch. On resistance is closely matched between switches

and very flat over the full signal range.

1. 3-Wire Serial Interface.

2. Single Supply Operation. The ADG738 and ADG739 are

fully speciﬁed and guaranteed with 3 V and 5 V supply rails.

3. Low On Resistance, 2.5 Ω typical.

4. Any conﬁguration of switches may be on or off at any one time.

5. Guaranteed Break-Before-Make Switching Action.

6. Small 16-lead TSSOP Package.

The ADG738 and ADG739 utilize a 3-wire serial interface that

is compatible with SPI™, QSPI™, MICROWIRE™, and some

DSP interface standards. The output of the shift register DOUT

enables a number of these parts to be daisy-chained. On power-up,

the internal shift register contains all zeros and all switches

are in the OFF state.

Each switch conducts equally well in both directions when on,

making these parts suitable for both multiplexing and demulti-

plexing applications. As each switch is turned on or off by a

separate bit, these parts can also be conﬁgured as a type of switch

array, where any, all, or none of the eight switches may be closed

at any time. The input signal range extends to the supply rails.

All channels exhibit break-before-make switching action,

preventing momentary shorting when switching channels.

The ADG738 and ADG739 are available in 16-lead TSSOP

packages.
