current, low-noise inputs allow a minimum of capaci-
tance to be used.
Piezoresistive transducers applications require many of
the same qualities. For those applications the
MAX4236/MAX4237 high CMRR, PSRR, and offset sta-
bility are also a good match.
A typical application for a piezoresistive transducer

amplifier
design
using
the
MAX4236/MAX4237 is shown in the Typical Application
Circuit.
In general, the MAX4236/MAX4237 are good compo-
nents for any application in which an amplifier with an
almost zero input current is required, including high-
precision, long time-constant integrators and electro-
chemical sensors.
Power Supplies
The MAX4236/MAX4237 can operate from a single
+2.4V to +5.5V power supply, or from ±1.2V to ±2.75V
power supplies. The power supply pin(s) must be
bypassed to ground with a 0.1F capacitor as close to
the pin as possible.
Layout and Physical Design
A good layout improves performance by decreasing
the amount of parasitic and stray capacitance, induc-
tance and resistance at the amplifier’s inputs, outputs,
and power-supply connections. Since parasitics might
be unavoidable, minimize trace lengths, resistor leads,
and place external components as close to the pins as
possible.
In high impedance, low input current applications, input
lines guarding and shielding, special grounding, and
other physical design and layout techniques, are
mandatory if good results are expected.
The negative effects of crosstalk, EMI and other forms
of interference and noise (thermal, acoustic, etc.) must
be accounted for and prevented beforehand for good
performance in the type of sensitive circuitry in which
the MAX4236/MAX4237 are likely to be used.
