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 ultra-small packages. The MAX4465/ MAX4467/MAX4469 are unity-gain stable and deliver a 200kHz gain bandwidth from only 24µA of supply cur­rent. The MAX4466/MAX4468 are decompensated for a minimum stable gain of +5V/V and provide a 600kHz gain bandwidth product. In addition, these amplifiers feature Rail-to-Rail®outputs, high A
VOL
,
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 5nA 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 5-pin SC70 package, while the single with shutdown MAX4467/MAX4468 and dual MAX4469 are available in the space-saving 8-pin SOT23 package.

Detailed Description
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 24µA of supply current. The MAX4466/MAX4468 have a mini­mum stable gain of +5V/V while providing a 600kHz 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 10kload and still typically swing within 16mV 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 low power applications. The MIC_BIAS pin provides a switched version of V
CC
to the bias components. Figure 3 shows
some typical values.
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 5nA, the output enters a high impedance state and the bias current to the microphone is switched off. Pull SHDN low to enable the amplifier. Do not leave SHDN unconnected. 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 ratio of differential-mode gain to common-mode 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
0.1µF 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.
