Ge n e ra l De s c rip t io n
Fe a t u re s
The MAX4578/MAX4579 are high-voltage, 8-channel
CMOS multiplexers. The MAX4578 and dual 4-channel
MAX4579 are ideal for precision ADC calibration and
system self-monitoring applications. These calibration
multip le xe rs (c a l-muxe s ) ha ve p re c is ion re s is tor-
dividers to generate accurate voltage ratios from an
input reference voltage. The reference ratios include
15/4096 and 4081/4096 of the external reference volt-
age, accurate to 15 bits, and 1/2(V+) and 5/8(V+ - V-),
accurate to 8 bits. The external reference voltage as
well as ground can also be switched to the output. The
MAX4578/MAX4579 have enable inputs and address
latching. All digital inputs have 0.8V and 2.4V logic
thresholds, ensuring both TTL- and CMOS-logic com-
patibility when using a single +12V or dual ±15V sup-
plies. Protection diodes at all inputs provide >2kV ESD
rating.

Note 1: Signals on NO_, COM_, EN, LATCH, CAL, A_ exceeding V+ or V- are clamped by internal diodes. Limit forward current to
maximum current ratings.
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.

they are reverse-biased differently. Each is biased by

either V+ or V- and the analog signal. This means their
leakage varies as the signal varies. The difference in
the two-diode leakage 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, which explains
how both sides of a given switch can show leakage cur-
rents of either the same or opposite polarity.
The MAX4578/MAX4579 are multiplexers with addition-
al calibration features. Internal resistor-dividers gener-
ate accurate voltage ratios from an external voltage
reference, allowing zero and full-scale calibration of
ADC systems, as well as facilitation of system self-mon-
itoring. To access the resistor-dividers, assert the CAL
pin. When CAL and ENABLE are asserted, the three
address pins select one of the various resistor-divider
or external reference outputs. The MAX4578/ MAX4579
also contain a LATCH input that allows the state of the
CAL and address signals to be captured.
The re is no c onne c tion b e twe e n the a na log -s ig na l
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 with V+ and V- by the logic-level translators.
Ca lib ra t io n Fu n c t io n s
The gain-divider, offset-divider, REFHI, and REFLO
modes allow calibration of offset and gain errors in
ADC systems. The gain-divider mode outputs a voltage
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 switch-

, also accurate to 0.1/4096. The REFHI mode
allows the voltage on the REFHI pin to be switched to
the output. The REFLO mode allows the voltage on the
REFLO pin to be switched to the output.
Increasing V- has no effect on the logic-level thresh-
olds, but it does increase the drive to the P-channel
switches, which reduces their on-resistance. V- also
sets the negative limit of the analog-signal voltage.
S e lf-Mo n it o rin g Fu n c t io n s
The self-monitoring functions are intended to allow an
ADC to measure its own supply voltage. The MAX4578
has an internal divide-by-two resistor string between V+
and GND that is accurate to 8 bits. It also has a 5/8
resistor string between V+ and V- that is accurate to 8
bits. This divider string allows measurement of the nega-
tive s up p ly with a unip ola r ADC. GND c a n a ls o b e
switched to the output, eliminating the need for an addi-
tional multiplexer channel.
The log ic -le ve l thre s hold s a re CMOS- a nd TTL-
compatible when V+ is greater than +4.5V.
Bip o la r-S u p p ly Op e ra t io n
The MAX4578/MAX4579 operate with bipolar supplies
between ±4.5V and ±20V. The V+ and V- supplies need
not be symmetrical, but their sum cannot exceed the
absolute maximum rating of 44V. Note: Do not connect
the MAX4578/MAX4579 V+ pin to +3V AND connect
logic-level input pins to TTL logic-level signals. TTL
logic-level outputs can exceed the absolute maximum
ratings, which will cause damage to the part and/or
external circuits.
__________ Ap p lic a t io n s In fo rm a t io n
The MAX4578/MAX4579’s construction is typical of
most CMOS analog switches. There are three supply
p ins : V+, V-, a nd GND. The p os itive a nd ne g a tive
power supplies provide drive to the internal CMOS
switches and set the limits of the analog voltage on any
s witc h. Re ve rs e -b ia s e d ESD p rote c tion d iod e s a re
internally connected between each analog signal pin
and both V+ and V-. If the voltage on any pin exceeds
V+ or V-, one of these diodes will conduct. During nor-
mal operation, these reverse-biased ESD diodes leak,
forming the only current drawn from V-.
S in g le -S u p p ly Op e ra t io n
The MAX4578/MAX4579 operate from a single supply
between +4.5V and +36V when V- is connected to GND.
All of the bipolar precautions must be observed (see
Bipolar Supply Operation section). However these parts
are optimized for ±15V operation, and most AC and DC
characteristics are degraded significantly when depart-
ing from ±15V. As the overall supply voltage (V+ to V-) is
lowered, switching speed, on-resistance, off-isolation,
and distortion will degrade, and supply current will
decrease (see the Typical Operating Characteristics
section).
Virtually all the analog leakage current is through the
ESD diodes. Although the ESD diodes on a given sig-
nal pin are identical, and therefore fairly well balanced,

Single-supply operation also limits signal levels and
P o w e r Off
When power to the MAX4578/MAX4579 is off (i.e., V+ =
V- = 0), the Absolute Maximum Ratings still apply. This
means that neither logic-level inputs on NO_ nor sig-
nals on COM_ can exceed ±0.3V. Voltages beyond
±0.3V cause the internal ESD-protection diodes to con-
duct, and the parts can be damaged if excessive cur-
rent flows.
interferes with ground referenced signals. When V- = 0,
AC signals are limited to -0.3V. Voltages below -0.3V
can be clipped by the internal ESD-protection diodes,
and the parts can be damaged if excessive current
flows.
P o w e r Up
During power up, on-chip latches will strobe whatever
addresses are present if EN goes high before LATCH
reaches a logic high. When this condition occurs, one
of the internal dividers connected between the supplies
may immediately turn on, causing higher supply current
(1.4mA) when the enable input is toggled. Avoid this
c ond ition b y e ns uring tha t EN s ta ys low until the
remaining logic inputs are valid. To accomplish this,
connect a resistor from EN to ground or apply a low
voltage to EN before the other logic inputs go high.
