Preamplifiers with Complete Shutdown  
5–MAX469  
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 ultra-small packages. The MAX4465/  
MAX4467/MAX4469 are unity-gain stable and deliver a  
200kHz gain bandwidth from only 24µA of supply cur-  
rent. The MAX4466/MAX4468 are decompensated for a  
minimum stable gain of +5V/V and provide a 600kHz  
gain bandwidth product. In addition, these amplifiers

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.
