Phase-Reversal Analog Switches
The MAX4526/MAX4527 are CMOS analog ICs configured as phase-reversal switches. The MAX4526 is
optimized for high-speed applications, such as chopper amplifiers, while the MAX4527 is optimized for
low-power applications.
The MAX4526/MAX4527 operate from a +4.5V to +36V
single supply or ±4.5V to ±18V dual supplies. On-resistance (175Ω max) is matched between switches to 8Ω
maximum. Each switch can handle rail-to-rail analog
signals. Maximum leakage current is only 0.5nA at
+25°C and 10nA at +85°C.
All digital inputs have 0.8V to 2.4V logic thresholds,
ensuring TTL/CMOS-logic compatibility.

_______________Detailed Description
The MAX4526/MAX4527 are phase-reversal analog
switches, consisting of two normally open and two normally closed CMOS analog switches arranged in a
bridge configuration. Analog signals are put into two
input pins and taken out of two output pins. A logiclevel signal controls whether the input signal is routed
through normally or inverted. A low-resistance DC path
goes from inputs to outputs at all times, yet isolation
between the two signal paths is excellent. Analog signals range from V- to V+.
These parts are characterized and optimized with ±15V
supplies, and they can operate from a single supply.
The MAX4526 is optimized for high-frequency operation, and has a higher-speed logic-level translator and
switch driver. The MAX4527 has identical analog switch
characteristics, but has a slower logic-level translator
and switch driver for lower current consumption.
The MAX4526/MAX4527 are designed for DC and lowfrequency-signal phase-reversal applications, such as
chopper amplifiers, modulator/demodulators, and selfzeroing or self-calibrating circuits. Unlike conventional
CMOS switches externally wired in a bridge configuration, both DC and AC symmetry are optimized with a
small 8-pin configuration that allows simple board layout and isolation of logic signals from analog signals.
FUNCTION
Positive Analog/Digital Supply-Voltage
Input. Internally connected to substrate.
Note: A, B, X and Y pins are identical and interchangeable.
Either may be considered as an input or output; signals pass
equally well in either direction. However, AC symmetry is best
when A and B are the input, and X and Y are the output.
Reduce AC balance in critical applications by using A and X or
A and Y as the input, and B and Y or B and X as the output.

OUTPUTS
Phase-Reversal Analog Switches
Overview
The MAX4526/MAX4527 construction is typical of most
CMOS analog switches. It has three supply pins: V+, V-,
and GND. V+ and V- drive the internal CMOS switches
and set the analog-voltage limits on any switch.
Reverse ESD-protection diodes are internally connected between each analog signal pin, and both V+ and
V-. One of these diodes conducts if any analog signal
exceeds V+ or V-.
Virtually all of the analog leakage current is through the
ESD diodes to V+ or V-. 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 either the same or opposite polarity.
There is no connection between the analog-signal paths
and GND. The analog-signal paths consist of an Nchannel 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
translator and set the input logic threshold. The logiclevel translator converts the logic levels to switched V+
and V- signals to drive the analog switches’ gates. This
drive signal is the only connection between GND and
the analog supplies. V+ and V- have ESD-protection
diodes to GND. The logic-level input has ESD protection to V+ and to V- but not to GND, so the logic signal
can go below GND (as low as V-) when bipolar supplies are used.
Increasing V- has no effect on the logic-level thresholds,
but it does increase the drive to the internal P-channel
switches, reducing the overall switch on-resistance. Valso sets the negative limit of the analog-signal voltage.
The logic-level input pin, IN, has ESD-protection diodes
to V+ and V- but not to GND, so it can be safely driven
to V+ and V-. The logic-level threshold, VIN, is CMOS/
TTL compatible when V+ is between 4.5V and 36V
(see Typical Operating Characteristics).
Bipolar Supplies
The MAX4526/MAX4527 operate with bipolar supplies
between ±4.5V and ±18V. However, since all factory
characterization is done with ±15V supplies, specifications at other supplies are not guaranteed. The V+ and
V- supplies need not be symmetrical, but their sum
cannot exceed the absolute maximum rating of 44V
(see Absolute Maximum Ratings).

Power-Supply Considerations
MAX4526/MAX4527
Phase-Reversal Analog Switches
Single Supply
The MAX4526/MAX4527 operate from a single supply
between +4.5V and +36V when V- is connected to
GND. Observe all of the bipolar precautions when
operating from a single supply.
__________Applications Information
The MAX4526/MAX4527 are designed for DC and
low-frequency-signal phase-reversal applications. Both
DC and AC symmetry are optimized for use with ±15V
supplies.
Signal Phase/Polarity Reversal
The MAX4526/MAX4527 can reverse the phase or
polarity of a pair of signals that are out-of-phase and
balanced to ground. This is done by routing signals
through the MAX4526/MAX4527 and under control of
the IN pin, reversing the two signals paths inside the
switch before sending out to a balanced output. Figure
1 shows a typical example. The MAX4526/MAX4527
cannot reverse the phase or polarity of a singlegrounded signal, as can be done with an inverting
op amp or transformer.
Balanced Modulators/Demodulators
The MAX4526/MAX4527 can be used as a balanced
modulator/demodulator at carrier frequencies up to
100kHz (Figure 2). Higher frequencies are possible, but
as frequency increases, small imbalances in the
MAX4526/MAX4527’s internal capacitance and resistance gradually impair performance. Similarly, imbalances in external circuit capacitance and resistance to
GND reduce overall carrier suppression.
The carrier is applied as a logic-level square wave to
IN. (Note that this voltage can go as negative as V-.)
For best carrier suppression, the power-supply voltages should be equal, the square wave should have a
precise 50% duty cycle, and both the input and output
signals should be symmetrical about ground. Bypass
V+ and V- to GND with 0.1µF ceramic capacitors, as
close to the IC pins as possible. Since the logic-level
translator/driver in the MAX4526 is faster than the one
in the MAX4527, it gives better results at higher
frequencies. In critical applications, carrier suppression
can be optimized by trimming duty cycle, DC bias
around GND, or external source and load capacitance.
In signal lines, balancing both capacitance and resistance to GND produces the best carrier suppression.
Transformer coupling of input and output signals
provides the best isolation and carrier suppression.
Transformers can also provide signal filtering, impedance matching, or low-noise voltage gain. Use a
center-tapped transformer or high-resistance voltage
divider to provide a DC path to GND on either the input
signal or output signal. This ensures a DC path to GND
and symmetrical operation of the internal switches.

V∆VOUT IS THE MEASURED VOLTAGE DUE TO CHARGE TRANSFER
ERROR Q WHEN THE CHANNEL TURNS OFF.
V- IS CONNECTED TO GND (0V) FOR SINGLE-SUPPLY OPERATION.
Q = ∆VOUT x CL

MEASUREMENTS ARE STANDARDIZED AGAINST SHORT AT SOCKET TERMINALS.
OFF ISOLATION IS MEASURED BETWEEN A, B AND "OFF" X, Y TERMINAL.
ON LOSS IS MEASURED BETWEEN A, B AND "ON" X, Y TERMINAL.
SIGNAL DIRECTION THROUGH SWITCH IS REVERSED; WORST VALUES ARE RECORDED.
V- IS CONNECTED TO GND (0V) FOR SINGLE-SUPPLY OPERATION.
