PRODUCT HIGHLIGHTS

1. 1.8 V to 5.5 V Single Supply Operation. The ADG749

offers high performance, including low on resistance and

fast switching times, and is fully specified and guaranteed

with 3 V and 5 V supply rails.

Mechanical Reed Relay Replacement

GENERAL DESCRIPTION

2. Very Low R_ON(5 Ω max at 5 V, 10 Ω max at 3 V). At 1.8 V

The ADG749 is a monolithic CMOS SPDT switch. This switch

is designed on a submicron process that provides low power

dissipation yet gives high switching speed, low on resistance and

low leakage currents.

operation, R_ONis typically 40 Ω over the temperature range.

3. On-Resistance Flatness (R_FLAT(ON)) (0.75 Ω typ).

4. –3 dB Bandwidth >200 MHz.

The ADG749 can operate from a single supply range of 1.8 V to

5.5 V, making it ideal for use in battery-powered instruments and

with the new generation of DACs and ADCs from Analog Devices.

5. Low Power Dissipation. CMOS construction ensures low

power dissipation.

6. Fast t_ON/t_OFF.

Each switch of the ADG749 conducts equally well in both

directions when on. The ADG749 exhibits break-before-make

switching action.

7. Tiny 6-lead SC70 package.

Because of the advanced submicron process, –3 dB bandwidths

of greater than 200 MHz can be achieved.

The ADG749 is available in a 6-lead SC70 package.
