MAX4504CPA
Low-Voltage / Dual-Supply / SPST / CMOS Analog Switches
_______________General DescriptionThe MAX4503/MAX4504 are low-voltage, dual-supply,
single-pole/single-throw (SPST), CMOS analog switch-
es. The MAX4503 is normally open (NO). The MAX4504
is normally closed (NC).
These CMOS switches can operate continuously with
dual supplies between ±1.V and ±6V. Each switch can
handle rail-to-rail analog signals. The off-leakage cur-
rent is only 1nA at +25°C or 10nA at +85°C.
The digital input is CMOS-logic compatible when using
±5V supplies. A unique logic input architecture allows
this even though the parts have no ground pin.
For single-supply operation, use the MAX4501/
MAX4502, which are pin-for-pin equivalents.

__________Applications Information
Power-Supply ConsiderationsThe MAX4503/MAX4504’s construction is typical of
most CMOS analog switches, except they have only
two supply pins: V+ and V-. These voltages set the
analog voltage limits of the switch. Reverse ESD-pro-
tection diodes are internally connected between IN and
each analog signal pin and both V+ and V-. If any ana-
log signal exceeds V+ or V-, one of these diodes will
conduct. During normal operation, these (and other)
reverse-biased ESD diodes leak, forming the only cur-
rent drawn from V-. Additional current flows through V+
from the logic-level translator.
Virtually all the analog leakage current is provided
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 will vary as the signal varies. The
differencein the two diode leakages to the V+ and V-
pins constitutes the analog-signal-path leakage current.
All analog leakage current flows between each pin and
one of the supply terminals, not to the other switch ter-
minal. This is why both sides of a given switch can
show leakage currents of either the same or opposite
polarity.
There is no connection between the analog signal
paths and V+ or V-.
V+ and V- also power the internal logic and logic-level
translators. Since there is no ground pin, the logic input
has a low-current pull-up to V+ and the logic limit is set
by an internal comparator referenced to V+. The logic-
level translators convert the logic levels to switched V+
and V- signals, to drive the gates of the analog signals.
This drive signal is the only connection between the
logic supplies (and signals) and the analog supplies.
COM, NO, and NC pins have ESD-protection diodes to
V+ and V-.
The logic is CMOS compatible when V+ is +5V. CMOS
compatibility is maintained with all V+ values, assuming
that the CMOS logic is operated from the same V+ sup-
ply. Since the MAX4503/MAX4504 have no ground
pins, the logic levels are internally referenced to V+.
Do not connect the MAX4503/MAX4504 V+ to +3V
and connect the logic-level pins to TTL-logic-level
signals. TTL levels can exceed +3V and violate the
absolute maximum ratings, damaging the part
and/or external circuits.
High-Frequency PerformanceIn 50Ωsystems, signal response is reasonably flat up
to 50MHz. (see Typical Operating Characteristics).
Above 20MHz the on-response has several minor
peaks which are highly layout dependent. The problem
is not in turning the switch on, but in turning it off. The
off-state switch acts like a capacitor, and passes higher
frequencies with less attenuation. At 10MHz, off isola-
tion is about -65dB in 50Ωsystems, becoming worse
(approximately 20dB per decade) as frequency
increases. Higher circuit impedances also make off iso-
lation worse.
