APPLICATIONS
Analog input/output modules
Process control/distributed control systems
Data acquisition
Instrumentation
Avionics
Automatic test equipment
Communication systems
The low on-resistance of these switches, combined with the
on-resistance flatness over a significant portion of the signal
range make them an ideal solution for data acquisition and
instrumentation applications where excellent linearity and low
distortion are critical.
GENERAL DESCRIPTION
The ADG5462F contains four channels that are overvoltage
protected. The channel protector is placed in series with the signal
path and protects sensitive components from overvoltage faults
in that path. The channel protector prevents overvoltages when
powered and unpowered, and it is ideal for use in applications
where correct power supply sequencing cannot always be guaranteed.
The primary supply voltages define the on-resistance profile,
while the secondary supply voltages define the voltage level at
which the overvoltage protection engages.
PRODUCT HIGHLIGHTS
1. Source pins (Sx) are protected against voltages greater than
the secondary supply rails (POSFV and NEGFV), up to
−55 V and +55 V.
2. In an unpowered state, source pins (Sx) are protected
against voltages from −55 V to +55 V.
3. Overvoltage detection with digital output indicates the
operating state of the channels.
4. Trench isolation guards against latch-up.
When no power supplies are present, the channel remains in the off
condition, and the channel inputs are high impedance. Under
normal operating conditions, if the analog input signal levels on
any Sx pin exceed positive fault voltage (POSFV) or negative fault
voltage (NEGFV) by a threshold voltage (VT), the channel turns
off and that Sx pin becomes high impedance. If the DR pin is
driven low, the drain pin (Dx) is pulled to the secondary supply
voltage that was exceeded. The output profile for each DR voltage
level is shown in Figure 49. Input signal levels up to −55 V or
+55 V relative to ground are blocked in both the powered and
unpowered conditions.
5. Optimized for low on-resistance and on-resistance flatness.
6. The ADG5462F operates from a dual power supply range of
5 V to 22 V or a single power supply range of 8 V to 44 V.

THEORY OF OPERATION
SWITCH ARCHITECTURE

Each channel of the ADG5462F consists of a parallel pair of
NDMOS and PDMOS transistors. This construction provides
excellent performance across the signal range. The ADG5462F
channels present only as a typical impedance of 10 Ω when input
signals with a voltage between POSFV and NEGFV are applied.

Additional internal circuitry enables the switch to detect
overvoltage inputs by comparing the voltage on the source
pin (Sx) with POSFV and NEGFV. A signal is considered
overvoltage if it exceeds the secondary supply voltages by the
voltage threshold (VT). The threshold voltage is typically 0.7 V,
but it ranges from 0.8 V at −40°C down to 0.6 V at +125°C. See
Figure 23 to see the change in VT with operating temperature.

Figure 49. Drain Output Response During Overvoltage Condition
During overvoltage conditions, the leakage current into and out
of the source pins (Sx) is limited to tens of microamperes. If the
DR pin is allowed to float or is driven high, only nanoamperes
of leakage are seen on the drain pins (Dx). If the DR pin is driven
low, the drain pin (Dx) is pulled to the rail. The device that pulls
the drain pin to the rail has an impedance of approximately 40 kΩ;
therefore, the Dx pin current is limited to about 1 mA during a
shorted load condition. This internal impedance also determines
the minimum external load resistance required to ensure that
the drain pin is pulled to the desired voltage level during a fault.
The maximum voltage that can be applied to any source input
is −55 V or +55 V. When the device is powered using a single
supply of 25 V or greater, the maximum negative signal level is
reduced. It reduces from −55 V at VDD = +25 V to −40 V at VDD
=
+40 V to remain within the 80 V maximum rating. Construction of
the silicon process allows the channel to withstand 80 V across
the switch when it is opened. These overvoltage limits apply
whether the power supplies are present or not.

Figure 48. Switch Channel and Control Function
When an overvoltage condition is detected on a source pin (Sx),
the switch automatically opens and the source pin (Sx) becomes
high impedance and ensures that no current flows through the
switch. If the DR pin is driven low, the drain pin (Dx) is pulled
to the supply that was exceeded. For example, if the source voltage
exceeds POSFV, the drain output pulls to POSFV. The same is
true for NEGFV. In Figure 27, the voltage on the drain pin (Dx)
clamps to the POSFV voltage when the source voltage exceeds
POSFV by VT. If the DR pin is allowed to float or is driven high,
the drain pin (Dx) also goes open circuit. In Figure 25, the voltage
on the drain pin (Dx) follows the voltage on the source pin
(Sx) until the switch turns off completely and the drain voltage
discharges through the load. The output response for each drain
pin configuration is shown in Figure 49. The maximum voltage
on the drain is limited by the internal ESD diodes and the rate
at which the output voltage discharges is dependent on the load at
the pin.
The drain pins (Dx) have ESD protection diodes to the secondary
supply rails, and the voltage at these pins must not exceed the
secondary supply voltage.
The source pins (Sx) have specialized ESD protection that allows
the signal voltage to reach 55 V with a 22 V dual supply, and
from −40 V to +55 V with a +40 V single supply. See Figure 48
for the switch channel overview. Exceeding 55 V on any source
input may damage the ESD protection circuitry on the device.

ADG5462F
Trench Isolation
The channel responds to an analog input that exceeds POSFV
or NEGFV by a threshold voltage (VT) by turning off. The absolute
input voltage limits are −55 V and +55 V, while maintaining an
80 V limit between the source pin (Sx) and the supply rails. The
switch remains off until the voltage at the source pin (Sx) returns to
between POSFV and NEGFV.
In the ADG5462F, an insulating oxide layer (trench) is placed
between the NDMOS and the PDMOS transistors of each channel.
Parasitic junctions, which occur between the transistors in junction
isolated switches, are eliminated, and the result is a switch that
is latch-up immune under all circumstances. This device passes
a JESD78D latch-up test of 500 mA for 1 sec, which is the
harshest test in the specification.
The fault response time (tRESPONSE) when powered by a 15 V dual
supply is typically 460 ns, and the fault recovery time (tRECOVERY) is
720 ns. These values vary with supply voltage and output load
conditions.
NDMOS
PDMOS
The maximum stress across the channel and between the source
pin (Sx) and any supply pin is 80 V; therefore, pay close attention
to this limit if using the device in a single-supply configuration and
a negative overvoltage is applied to the device.
For example, consider the case where the device is set up in a
single supply configuration, as shown in Figure 51.

USER DEFINED FAULT PROTECTION
These calculations are all within device specifications: 55 V
maximum fault on source inputs and a maximum of 80 V
across the channel or to a supply pin. The voltage on a source
pin (Sx) cannot go below −44 V to stay within +80 V maximum.
POSFV and NEGFV are required secondary power supplies
that set the level at which the overvoltage protection is engaged.
POSFV can be supplied from 4.5 V up to VDD, and NEGFV can
be supplied from VSS to 0 V. If a secondary supply is not available,
these pins (POSFV and NEGFV) must be connected to VDD
(POSFV) and VSS (NEGFV). The overvoltage protection then
engages at the primary supply voltages. When the voltages at
the source inputs exceed POSFV or NEGFV by VT, the channel
turns off or, if the device is unpowered, the channel remains off.
The source input remains high impedance, and if the DR pin is
driven low, the drain pulls to either POSFV or NEGFV. Signal
levels up to −55 V and +55 V are blocked in both the powered
and unpowered condition as long as the 80 V limitation between
the source and supply pins is met.

Power-Off Protection
Overvoltage Interrupt Flag
When no power supplies are present, the channel remains in the
off condition, and the switch inputs are high impedance. This
state ensures that no current flows and prevents damage to the
switch or downstream circuitry. The switch output is a virtual
open circuit.
The voltages on the source inputs of the ADG5462F are
continuously monitored, and an active low digital output pin
(FF) indicates the state of the switches.
The voltage on the FF pin indicates if any of the source input pins
are experiencing a fault condition. The output of the FF pin is a
nominal 3 V when all source pins (Sx) are within normal operating
range. If any source pin (Sx) voltage exceeds the supply voltage
by VT, the FF output reduces to below 0.8 V.
The switch remains off regardless of whether the primary and
secondary supplies are 0 V or floating. A GND reference must
always be present to ensure proper operation. Signal levels of up
to 55 V are blocked in the unpowered condition.
Digital Input Protection
The ADG5462F can tolerate digital input signals being present
on the device without power. The digital input is protected against
positive faults up to 44 V. The digital input does not offer protection
against negative overvoltages. ESD protection diodes connected
to GND are present on the digital input.

APPLICATIONS INFORMATION
The overvoltage protected family of switches and multiplexers

automotive, aerospace, and other harsh environments where
overvoltage signals can be present, and the system must remain

POWER SUPPLY RAILS
To guarantee correct operation of the device, 0.1 μF decoupling
capacitors are required on the primary and secondary supplies.
If they are driven from the same supply, then one set of 0.1 μF
decoupling capacitors is sufficient.
USER DEFINED SIGNAL RANGE
The primary supplies define the on-resistance profile of the
channels, while the secondary supplies define the signal range.
Using voltages on POSFV and NEGFV that are lower than VDD
and VSS, the required signal can benefit from the flat on resistance
in the center of the full signal capabilities of the device.
The secondary supplies (POSFV and NEGFV) provide the
current required to operate the fault protection and, therefore,
must be low impedance supplies. Therefore, they can be derived
from the primary supply by using a resistor divider and buffer.
LOW IMPEDANCE CHANNEL PROTECTION
The ADG5462F can be used as a protective element in signal
chains that are sensitive to both channel impedance and
overvoltage signals. Traditionally, series resistors are used to
limit the current during an overvoltage condition to protect
susceptible components.
The secondary supply rails (POSFV and NEGFV) must not exceed
the primary supply rails (VDD and VSS) because this can lead to a
signal passing through the switch unintentionally.
The ADG5462F can operate with bipolar supplies between 5 V
and 22 V. The supplies on VDD and VSS need not be symmetrical
but the VDD and VSS range must not exceed 44 V. The ADG5462F
can also operate with single supplies between 8 V and 44 V with
VSS connected to GND.
These series resistors affect the performance of the signal chain
and reduce the precision that can be reached. A compromise
must be reached on the value of the series resistance that is high
enough to sufficiently protect sensitive components but low
enough that the precision performance of the signal chain is not
sacrificed.
The ADG5462F is fully specified at 15 V, 20 V, +12 V, and
+36 V supply ranges.
POWER SUPPLY SEQUENCING PROTECTION
The ADG5462F enables the designer to remove these resistors
and retain the precision performance without compromising
the protection of the circuit.
The channels remain open when the device is unpowered and
signals from −55 V to +55 V can be applied without damaging
the device. Only when the supplies are connected, and the signal
is within normal operating range, do the channels close. Placing
the ADG5462F between external connectors and sensitive
components offers protection in systems where a signal is
presented to the source pins (Sx) before the supply voltages
are available.
HIGH VOLTAGE SURGE SUPPRESSION
The ADG5462F is not intended for use in very high voltage
applications. The maximum operating voltage of the transistor
is 80 V. In applications where the inputs are likely to be subject
to overvoltages exceeding the breakdown voltage, use transient
voltage suppressors (TVSs) or similar.
POWER SUPPLY RECOMMENDATIONS
Analog Devices, Inc., has a wide range of power management
products to meet the requirements of most high performance
signal chains.
An example of a bipolar power solution is shown in Figure 52.
The ADP7118 and ADP7182 can be used to generate clean
positive and negative rails from the dual switching regulator
output. These rails can power the ADG5462F, an amplifier,
and/or a precision converter in a typical signal chain.

Data Sheet
The interrupt flag recovery time, tDIGREC, can be decreased from
a typical 60 µs to 600 ns by using a 1 kΩ pull-up resistor.
INTELLIGENT FAULT DETECTION
The ADG5462F digital output pin (FF) can interface with a
microprocessor or control system and be used as an interrupt
flag. This feature provides real-time diagnostic information on
the state of the device and the system to which it connects.
The DR pin can also be used for diagnostic purposes. The FF
pin provides an interrupt that indicates one of the four channels
has a fault. The DR pin can then be pulled low to find which of
the channels has a fault as well as the polarity of the fault. For
example, if an ADC downstream is monitoring the channel, a
full-scale reading then indicates a positive fault, and a zero-scale
reading indicates a negative fault.
The control system can use the digital interrupt to start a
variety of actions, such as
•

Signaling the data recorders to mark data during these
events as unreliable or out of specification
LARGE VOLTAGE, HIGH FREQUENCY SIGNALS
Figure 24 illustrates the voltage range and frequencies that the
ADG5462F can reliably convey. For signals that extend across
the full signal range from VSS to VDD, keep the frequency less
than 3 MHz. If the required frequency is greater than 3 MHz,
decrease the signal range appropriately to ensure signal integrity.
For systems that are sensitive during a start-up sequence, the
active low operation of the flag allows the system to ensure that
the ADG5462F is powered on and that all input voltages are
within normal operating range before initiating operation.
The FF pin is a weak pull-up, which allows the signals to be
