Product Summary

The LMV1032URX-25 is an audio amplifier for 3-Wire Analog Electret Microphones. It is designed to replace the JFET preamp currently being used. The LMV1032URX-25 is ideal for extended battery life applications, such as a Bluetooth communication link. The addition of a third pin to an electret microphone that incorporates an LMV1032 allows for a dramatic reduction in supply current as compared to the JFET equipped electret microphone. Microphone supply current is thus reduced to 60μA, assuring longer battery life. It is guaranteed for supply voltages from 1.7V to 5V, and has fixed voltage gains of 6 dB, 15dB and 25dB. The applications of the LMV1032URX-25 include Mobile communications - Bluetooth, Automotive accessories, Cellular phones, PDAs, Accessory microphone products.
