GENERAL DESCRIPTION
PRODUCT HIGHLIGHTS
The ADG736 is a monolithic device comprising two independ-
ently selectable CMOS single pole, double throw (SPDT) switches.
These switches are designed using a submicron process that
provides low power dissipation yet gives high switching speed,
low on resistance, low leakage currents, and wide input signal
bandwidth.
1. 1.8 V to 5.5 V Single-Supply Operation. The ADG736
offers high performance, including low on resistance and
fast switching times. It is fully specified and guaranteed
with 3 V and 5 V supply rails.
2. Very Low RON (4.5 Ω Maximum at 5 V, 8 Ω Maximum at 3 V).
At a supply voltage of 1.8 V, RON is typically 35 Ω over the
temperature range.
3. Low On Resistance Flatness.
4. −3 dB Bandwidth > 200 MHz.
5. Low Power Dissipation. CMOS construction ensures low
power dissipation.
The on resistance profile is very flat over the full analog signal
range. This ensures excellent linearity and low distortion when
switching audio signals. Fast switching speed also makes the
part suitable for video signal switching.
The ADG736 operates from a single 1.8 V to 5.5 V supply,
making it ideally suited to portable and battery-powered
instruments.
6. Fast tON/tOFF
.
7. Break-Before-Make Switching Action.
8. 10-Lead MSOP Package.
Each switch conducts equally well in both directions when on, and
each has an input signal range that extends to the power supplies.
The ADG736 exhibits break-before-make switching action.
The ADG736 is available in a 10-lead MSOP package.
