More Information
The LMV1031 audio amplifier is an ideal replacement for the JFET preamplifier that is currently used in the electret microphones. The LMV1031 is optimized for applications that require extended battery life, such as Bluetooth communication links. The supply current for the LMV1031 is only 72 μA. This is a dramatic reduction from that required for a JFET equipped microphone. The LMV1031, with its separate output and supply pins, offers a higher PSRR and eliminates the need for additional external components.
