The LMV1014 is an audio amplifier for small form factor electret microphones. It is designed to replace the JFET preamp currently being used. The LMV1014 is ideal for extended battery life applications, such as a bluetooth communication link. The addition of a third pin in electret microphones that incorporate the LMV1014 allows for a dramatic reduction in supply current as compared to the JFET-equipped electret microphone. Microphone supply current is thus reduced to 38A assuring longer battery life. The LMV1014 is guaranteed for supply voltages from 1.7V to 5V, and has a fixed voltage gain of 6dB.
