GENERAL DESCRIPTION
PRODUCT HIGHLIGHTS
The ADG736 is a monolithic device comprising two indepen-
dently selectable CMOS SPDT switches. These switches are
designed on a submicron process that provides low power dissi-
pation 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 and is fully specified and
guaranteed with +3 V and +5 V supply rails.
2. Very Low RON (4.5 Ω Max at 5 V, 8 Ω Max at 3 V).
At supply voltage of +1.8 V, RON is typically 35 Ω over the
temperature range.
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.
3. Low On-Resistance Flatness.
4. –3 dB Bandwidth >200 MHz.
The ADG736 can operate from a single +1.8 V to +5.5 V sup-
ply, making it ideally suited to portable and battery powered
instruments.
5. Low Power Dissipation.
CMOS construction ensures low power dissipation.
6. Fast tON/tOFF
.
Each switch conducts equally well in both directions when on
and has an input signal range that extends to the power supplies.
The ADG736 exhibits break-before-make switching action.
7. Break-Before-Make Switching Action.
8. 10-Lead µSOIC Package.
The ADG736 is available in a 10-lead µSOIC package.
