GENERAL DESCRIPTION
PRODUCT HIGHLIGHTS
The ADG736 is a monolithic device comprising two independently 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.
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.

8.
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.
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.
Low On Resistance Flatness.
−3 dB Bandwidth > 200 MHz.
Low Power Dissipation. CMOS construction ensures low
power dissipation.
Fast tON/tOFF.
Break-Before-Make Switching Action.
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.

TERMINOLOGY
tOFF
Delay between applying the digital control input and the output
switching off. See Figure 13.
RON
Ohmic resistance between Terminal D and Terminal S.
∆RON
On resistance match between any two channels; that is, RON
maximum − RON minimum.
RFLAT (ON)
Flatness is defined as the difference between the maximum and
minimum value of on resistance as measured over the specified
analog signal range.
IS (Off)
Source leakage current with the switch off.
tD
Off time or on time measured between the 90% points of both
switches, when switching from one address state to another. See
Figure 14.
Crosstalk
A measure of unwanted signal that is coupled from one channel
to another as a result of parasitic capacitance.
Off Isolation
A measure of unwanted signal coupling through an off switch.
ID, IS (On)
Channel leakage current with the switch on.
Bandwidth
The frequency at which the output is attenuated by −3 dB.
VD (VS)
Analog voltage on Terminal D and Terminal S.
On Response
The frequency response of the on switch.
CS (Off)
Off switch source capacitance.
CD, CS (On)
On switch capacitance.
tON
Delay between applying the digital control input and the output
switching on. See Figure 13.
On Loss
The voltage drop across the on switch, seen on the on response
vs. frequency plot (see Figure 7) as how many decibels (dB) the
signal is away from 0 dB at very low frequencies.
