Low-Cost, Micropower, SC70/SOT23-8, Microphone  
Preamplifiers with Complete Shutdown  
General Description  
Features  
The MAX4465–MAX4469 are micropower op amps opti-  
mized for use as microphone preamplifiers. They pro-  
vide 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 cur-  
rent. The MAX4466/MAX4468 are decompensated for a  
minimum stable gain of +5V/V and provide a 500kHz  
gain bandwidth product. In addition these amplifiers  
o +2.4V to +5.5V Supply Voltage Operation  
o Version with 10nA Shutdown Available  
(MAX4467/MAX4468)  
o Excellent Power-Supply Rejection Ratio: 112dB  
o Excellent Common-Mode Rejection Ratio: 80dB  
o Rail-to-Rail Outputs  
o Gain Bandwidth Product:  
®
feature Rail-to-Rail outputs, plus excellent power-sup-  
200kHz (MAX4465/MAX4467/MAX4469)  
500kHz (MAX4466/MAX4468)  
ply rejection and common-mode rejection ratios for  
operation in noisy environments.  
o Low 20µA Quiescent Supply Current  
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.  
o Available in Space-Saving Packages  
5-Pin SC70 (MAX4465/MAX4466)  
8-Pin SOT23 (MAX4467/MAX4468/MAX4469)
