GENERAL DESCRIPTION
The ADG708/ADG709 are low voltage, CMOS analog
multiplexers comprising eight single channels and four
differential channels, respectively. The ADG708 switches one of
eight inputs (S1 to S8) to a common output, D, as determined
by the 3-bit binary address lines A0, A1, and A2. The ADG709
switches one of four differential inputs to a common differential
output as determined by the 2-bit binary address lines A0 and
A1. An EN input on both devices is used to enable or disable
the device. When disabled, all channels are switched off.
Low power consumption and an operating supply range of
1.8 V to 5.5 V make the ADG708/ADG709 ideal for battery-
powered, portable instruments. All channels exhibit break-
before-make switching action preventing momentary shorting
when switching channels.
These switches are designed on an enhanced submicron process
that provides low power dissipation yet gives high switching
speed, very low on resistance, and leakage currents.
On resistance is in the region of a few ohms and is closely matched
between switches and very flat over the full signal range. These parts
can operate equally well as either multiplexers or demultiplexers
and have an input signal range that extends to the supplies.

TERMINOLOGY
VDD
Most positive power supply potential.
VSS
Most negative power supply in a dual-supply application. In
single-supply applications, tie VSS to ground at the device.
GND
Ground (0 V) reference.
S
Source terminal. Can be an input or output.
D
Drain terminal. Can be an input or output.
Ax
Logic control input.
EN
Active high enable.
RON
Ohmic resistance between D and S.
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.
ID (Off)
Drain leakage current with the switch off.
ID, IS (On)
Channel leakage current with the switch on.
VD (VS)
Analog voltage on Terminal D and Terminal S.
CS (Off)
Off switch source capacitance. Measured with reference to ground.
CD (Off)
Off switch drain capacitance. Measured with reference to ground.
CD, CS (On)
On switch capacitance. Measured with reference to ground.
CIN
Digital input capacitance.
tTRANSITION
Delay time measured between the 50% and 90% points of the
digital inputs and the switch on condition when switching from
one address state to another.
tON (EN)
Delay time between the 50% and 90% points of the EN digital
input and the switch on condition.
tOFF (EN)
Delay time between the 50% and 90% points of the EN digital
input and the switch off condition.
tOPEN
Off time measured between the 80% points of both switches
when switching from one address state to another.
Off Isolation
A measure of unwanted signal coupling through an off switch.
Crosstalk
A measure of unwanted signal that is coupled through from one
channel to another as a result of parasitic capacitance.
Charge
A measure of the glitch impulse transferred from injection of
the digital input to the analog output during switching.
Bandwidth
The frequency at which the output is attenuated by 3 dB.
On Response
The frequency response of the on switch.
On Loss
The loss due to the on resistance of the switch.
VINL
Maximum input voltage for Logic 0.
VINH
Minimum input voltage for Logic 1.
IINL (IINH)
Input current of the digital input.
IDD
Positive supply current.
ISS
Negative supply current.

APPLICATIONS INFORMATION
POWER SUPPLY SEQUENCING
When using CMOS devices, take care to ensure correct power
supply sequencing. Incorrect power supply sequencing can
result in the device being subjected to stresses beyond the
maximum ratings listed in Figure 4.
Always apply digital and analog inputs after power supplies and
ground. For single-supply operation, tie VSS to GND as close to
the device as possible.
