MAX4465–MAX4469
General Description
The MAX4465–MAX4469 are micropower op amps optimized for use as microphone preamplifiers. They provide the ideal combination of an optimized gain
bandwidth product vs. supply current, and low-voltage
operation in an ultra-small package. The MAX4465/
MAX4467/MAX4469 are unity-gain stable and deliver a
200kHz gain bandwidth from only 20µA of supply current. The MAX4466/MAX4468 are decompensated for a
minimum stable gain of +5V/V and provide a 500kHz
gain bandwidth product. In addition these amplifiers
feature Rail-to-Rail® outputs, plus excellent power-supply rejection and common-mode rejection ratios for
operation in noisy environments.
The MAX4467/MAX4468 include a complete shutdown
mode. In shutdown, the amplifiers’ supply current is
reduced to 10nA and the bias current to the external
microphone is cut off for ultimate power savings. The
single MAX4465/MAX4466 are offered in the ultra-small
SC70-5 package, while the single with shutdown
MAX4467/MAX4468 and dual MAX4469 are available in
the space-saving SOT23-8 package.

Low-Cost, Micropower, SC70/SOT23-8, Microphone
Preamplifiers with Complete Shutdown
The MAX4465–MAX4469 are low-power, micropower
op amps designed to be used as microphone preamplifiers. These preamplifiers are an excellent choice for
noisy environments because of their high commonmode rejection and excellent power-supply rejection
ratios. They operate from a single +2.4V to +5.5V supply.
The MAX4465/MAX4467/MAX4469 are unity-gain stable
and deliver a 200kHz gain bandwidth from only 20µA of
supply current. The MAX4466/MAX4468 have a minimum stable gain of +5V/V while providing a 500kHz
gain bandwidth product.
The MAX4467/MAX4468 feature a complete shutdown,
which is active-high, and a shutdown-controlled output
providing bias to the microphone. The MAX4465/
MAX4467/MAX4469 feature a slew rate suited to voice
channel applications. The MAX4466/MAX4468 can be
used for full-range audio, e.g., PC99 inputs.
Rail-to-Rail Output Stage
The MAX4465–MAX4469 can drive a 10kΩ load and
still typically swing within 20mV of the supply rails.
Figure 1 shows the output voltage swing of the
MAX4465 configured with AV = +10.
Switched Bias Supply
When used as a microphone amplifier for an electret
microphone, some form of DC bias for the microphone
is necessary. The MAX4467/MAX4468 have the ability
to turn off the bias to the microphone when the device
is in shutdown. This can save several hundred microamps of supply current, which can be significant in lowpower applications. The MIC_BIAS pin provides a
switched version of VCC to the bias components. Figure 3
shows some typical values.
the amplifier. Do not leave SHDN floating. Figure 5
shows the shutdown waveform.
Common-Mode Rejection Ratio
A microphone preamplifier ideally only amplifies the
signal present on its input and converts it to a voltage
appearing at the output. When used in noninverting
mode, there is a small output voltage fluctuation when
both inputs experience the same voltage change in the
common mode. The ratio of these voltages is called the
common-mode gain. The common-mode rejection ratio
is the logarithm of differential-mode gain to commonmode gain. The high CMRR properties of the
MAX4465–MAX4469 provide outstanding performances
when configured as a noninverting microphone preamplifier.
Power-Up
The MAX4465–MAX4469 outputs typically settle within
1µs 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
1µF 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 available, the MAX4465–MAX4469 should be connected to
the analog ground.
Driving Capacitive Loads
Driving a capacitive load can cause instability in many
op amps, especially those with low quiescent current.
The MAX4465/MAX4467/MAX4469 are unity-gain stable
for a range of capacitive loads up to 100pF. Figure 4
shows the response of the MAX4465 with an excessive
capacitive load.
Applications Information
Shutdown Mode
The MAX4467 and MAX4468 feature a low-power, complete shutdown mode. When SHDN goes high, the supply current drops to 10nA, the output enters a
high-impedance state and the bias current to the
microphone is switched off. Pull SHDN low to enable
