MAXIM MAX4522CPE

19-1136; Rev 6; 7/07
Quad, Low-Voltage, SPST Analog Switches
Features
The MAX4521/MAX4522/MAX4523 are quad, low-voltage, single-pole/single-throw (SPST) analog switches.
On-resistance (100Ω max) is matched between switches to 4Ω max, and is flat (12Ω max) over the specified
signal range. Each switch can handle rail-to-rail analog
signals. The off-leakage current is only 1nA at +25°C
and 10nA at +85°C.
♦ +2V to +12V Single Supply
±2V to ±6V Dual Supplies
The MAX4521 has four normally closed (NC) switches,
and the MAX4522 has four normally open (NO) switches. The MAX4523 has two NC switches and two NO
switches.
These CMOS switches can operate with dual power
supplies ranging from ±2V to ±6V or a single supply
between +2V and +12V. They are fully specified for single +2.7V operation.
All digital inputs have +0.8V and +2.4V logic thresholds, ensuring TTL/CMOS-logic compatibility when
using ±5V or a single +5V supply.
♦ Rail-to-Rail Signal Handling
♦ 100Ω Signal Paths with ±5V Supplies
♦ Low Power Consumption, <1µW
♦ 4 Separately Controlled SPST Switches
♦ Pin Compatible with Industry-Standard
DG211/DG212/DG213
♦ >2kV ESD Protection per Method 3015.7
♦ TTL/CMOS-Compatible Inputs with ±5V or
Single +5V Supply

Note 1: Signals on NC_, NO_, COM_, or IN_ exceeding V+ or V- are clamped by internal diodes. Limit forward-diode current to maximum current rating.
Note 2: All leads are soldered or welded to PC boards.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Note 3: The algebraic convention is used in this data sheet; the most negative value is shown in the minimum column.
Note 4: Guaranteed by design.
Note 5: ΔRON = ΔRON(MAX) - ΔRON(MIN).
Note 6: Resistance flatness is defined as the difference between the maximum and minimum on-resistance values, as measured
over the specified analog signal range.
Note 7: Leakage parameters are 100% tested at maximum rated temperature, and guaranteed by correlation at TA = +25°C.
Note 8: Off-Isolation = 20log10 [ VCOM_ / (VNC_ or VNO_) ], VCOM_ = output, VNC_ or VNO_ = input to off switch.
Note 9: Between any two switches.
Note 10: Leakage testing for single-supply operation is guaranteed by testing with dual supplies.

Typical Operating Characteristics (continued)

Quad, Low-Voltage, SPST Analog Switches
Applications Information
Power-Supply Considerations
Overview
The MAX4521/MAX4522/MAX4523 construction is typical of most CMOS analog switches. They have three
supply pins: V+, V-, and GND. V+ and V- are used to
drive the internal CMOS switches, and they set the limits of the analog voltage on any switch. Reverse ESDprotection diodes are internally connected between
each analog-signal pin and both V+ and V-. If any analog signal exceeds V+ or V-, one of these diodes conducts. During normal operation these reverse-biased
ESD diodes leak, forming the only current drawn from
V+ or V-.
Virtually all the analog leakage current is through the
ESD diodes. Although the ESD diodes on a given signal pin are identical and therefore fairly well balanced,
they are reverse biased differently. Each is biased by
either V+ or V- and the analog signal. This means their
leakages vary as the signal varies. The difference in the
two diode leakages from the signal path to the V+ and
V- pins constitutes the analog-signal-path leakage current. All analog leakage current flows to the supply terminals, not to the other switch terminal. This explains
how both sides of a given switch can show leakage
currents of the same or opposite polarity.
There is no connection between the analog-signal
paths and GND. The analog-signal paths consist of an
N-channel and P-channel MOSFET with their sources
and drains paralleled, and their gates driven out of
phase to V+ and V- by the logic-level translators.
V+ and GND power the internal logic and logic-level
translators, and set the input logic thresholds. The
logic-level translators convert the logic levels to
switched V+ and V- signals to drive the gates of the
analog switches. This drive signal is the only connection between the logic supplies and the analog supplies. V+ and V- have ESD-protection diodes to GND.
The logic-level inputs and output have ESD protection
to V+ and to GND.
Increasing V- has no effect on the logic-level thresholds, but it does increase the drive to the P-channel
switches, reducing their on-resistance. V- also sets the
negative limit of the analog-signal voltage.
8
The logic-level thresholds are CMOS/TTL compatible
when V+ = +5V. The threshold increases slightly as V+
is raised, and when V+ reaches +12V, the level threshold is about 3.1V. This is above the TTL output highlevel minimum of 2.8V, but still compatible with CMOS
outputs.
Bipolar Supplies
The MAX4521/MAX4522/MAX4523 operate with bipolar
supplies between ±2V and ±6V. The V+ and V- supplies need not be symmetrical, but their sum cannot
exceed the absolute maximum rating of 13.0V. Do not
connect the MAX4521/MAX4522/MAX4523 V+ to +3V,
and then connect the logic-level-input pins to TTL
logic-level signals. TTL logic-level outputs in excess
of the absolute maximum ratings can damage the
part and/or external circuits.
Caution: The absolute maximum V+ to V- differential
voltage is 13.0V. Typical ±6V or 12V supplies with
±10% tolerances can be as high as 13.2V. This voltage
can damage the MAX4521/MAX4522/MAX4523. Even
±5% tolerance supplies may have overshoot or noise
spikes that exceed 13.0V.
Single Supply
The MAX4521/MAX4522/MAX4523 operate from a
single supply between +2V and +12V when V- is connected to GND. All of the bipolar precautions must be
observed.
High-Frequency Performance
In 50Ω systems, signal response is reasonably flat up
to 50MHz (see Typical Operating Characteristics).
Above 20MHz, the on-response has several minor
peaks that are highly layout dependent. The problem
with high-frequency operation is not turning the switch
on, but turning it off. The off-state switch acts like a
capacitor and passes higher frequencies with less
attenuation. At 10MHz, off-isolation is about -52dB in
50Ω systems, becoming worse (approximately 20dB
per decade) as frequency increases. Higher circuit
impedances also make off-isolation worse. Adjacent
channel attenuation is about 3dB above that of a bare
IC socket, and is due entirely to capacitive coupling.
