GENERAL DESCRIPTION
The AD7SIODI, AD7SIlDI and AD7512DI are a family of
latch proof dielectrically isolated CMOS switches featuring over-
voltage protection up to t 25V above the power supplies. These
benefits are obtained without sacrificing the low "ON" resistance
(75n) or low leakage current (SOOpA), the main features of an
analog switch.
The AD7510DI and AD7511DI consist of four independent
SPST analog switches packaged in either a 16-pin DIP or a 20-
terminal surface mount package. They differ only in that the
digital control logic is inverted. The AD7512DI has two inde-
pendent SPDT switches packaged either in a 14-pin DIP or a
20-terminal surface mount package.
Very low power dissipation, overvoltage protection and TTL/
CMOS direct interfacing are achieved by combining a unique
circuit design and a dielectrically isolated CMOS process. Silicon
nitride passivation ensures long term stability while monolithic
construction provides reliability.

Figure f. Typical Output Switch Circuitry of AD75100/ Series
CIRCUIT DESCRIPTION
CMOS devices make excellent analog switches; however, problems
with overvoltage and latch-up phenomenon necessitated protection
circuitry. These protection circuits, however, either caused
degradation of important switch parameters such as Ros
or leakage, or provided only limited protection in the event of
overvoltage.
The AD7510DI series switches utilize a dielectrically isolated
CMOS fabrication process to eliminate the four-layer substrate
found in iunction-isolated CMOS, thus providing latch-free
operation.
A typical switch channel is shown in Figure 2. The output
switching element is comprised of device numbers 4 and 5.
Operation is as follows: for an "ON" switch, (in +) is Voo and
(in -) is Vss from the driver circuits. Device numbers 1 and 2
are "OFF" and number 3 in "ON". Hence, the backgates of the
P- and N-channel output devices (numbers 4 and S) are tied
together and floating. The circled devices are located in separate
dielectrically isolated pockets. Floating the output switch backgates
with the signal input increases the effective threshold voltage for
an applied analog signal, thus providing a flatter RON versus Vs
response.
For an "OFF" switch, device number 3 is "OFF," and the
backgates of devices 4 and S are tied through lkn resistors (R1
and R2) to the respective supply voltages through the "ON"
devices 1 and 2.
If a voltage is applied to the S or D (OUT) terminal which
exceeds Voz, or Vss, the S- or D-to-backgate diode is forward
biased; however, R1 and R2 provide current limiting action to
the supplies.
An equivalent circuit of the output switch element in Figure 3
shows that, indeed, the 1kft limiting resistors are in series with
the backgates of the P- and N-channel output devices - not in
series with the signal path between the S and D terminals.
It is possible to turn on an "OFF" switch by applying a voltage
in excess of VDD or Vss to the S or D terminal. If a positive
stress voltage is applied to the S or D terminal which exceeds
VDD by a threshold, then the P-channel (device 5) will turn on
creating a low impedance path between the S and D terminals.
A similar situation exists for negative stress voltages which
exceed Vss. In this case the N-channel provides the low impedance
path between the S and D terminals. The limiting factor on the
overvoltage protection is the power dissipation of the package
and is t 20V continuous (or 20mA whichever occurs first) above
the supply voltages.
