common mode. The ratio of these voltages is called the
common-mode gain. The common-mode rejection ratio
is the ratio of differential-mode gain to common-mode
gain.

of
the
MAX4465–MAX4469 provide outstanding performances
when configured as a noninverting microphone pream-
plifier.
Power-Up
The MAX4465–MAX4469 outputs typically settle within
1s after power-up. Figure 6 shows the output voltage
on power-up.
Power Supplies and Layout
The MAX4465–MAX4469 operate from a single +2.4V to
+5.5V power supply. Bypass the power supply with a
0.1F capacitor to ground. Good layout techniques are
necessary for the MAX4465–MAX4469 family. To
decrease stray capacitance, minimize trace lengths by
placing external components close to the op amp’s
pins. Surface-mount components are recommended. In
systems where analog and digital grounds are avail-
able, the MAX4465–MAX4469 should be connected to
the analog ground.
