GENERAL DESCRIPTION
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.
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.
Each switch of the ADG749 conducts equally well in both
directions when on. The ADG749 exhibits break-before-make
switching action.
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.

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.
2. Very Low R_ON (5 Ω max at 5 V, 10 Ω max at 3 V). At 1.8 V
operation, R_ON is typically 40 Ω over the temperature range.
3. On-Resistance Flatness (R_FLAT(ON)) (0.75 Ω typ).
4. –3 dB Bandwidth >200 MHz.
5. Low Power Dissipation. CMOS construction ensures low
power dissipation.
6. Fast t_ON/t_OFF.
7. Tiny 6-lead SC70 package.
