Figure 1. Typical Application Circuits
Phase-Reversal Analog Switches
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.

INPUTS
The MAX4526/MAX4527 are phase-reversal analog
switches, consisting of two normally open and two nor-
mally 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 logic-
level 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 sig-
nals 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 opera-
tion, 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 low-
frequency-signal phase-reversal applications, such as
chopper amplifiers, modulator/demodulators, and self-
zeroing or self-calibrating circuits. Unlike conventional
CMOS switches externally wired in a bridge configura-
tion, both DC and AC symmetry are optimized with a
small 8-pin configuration that allows simple board lay-
out and isolation of logic signals from analog signals.
