The Texas Instruments LMV1032URX-25 is an analog input microphone preamplifier series designed to replace traditional JFET preamps in small form factor electret microphones. This series is ideal for applications requiring extended battery life, such as Bluetooth communication links.
The LMV1032 series offers a low supply current of 60 μA, significantly reducing power consumption compared to JFET-equipped microphones and ensuring longer battery life. It is specified for supply voltages from 1.7V to 5V and provides fixed voltage gains of 6 dB, 15 dB, and 25 dB. The device exhibits low output impedance over the voice bandwidth, excellent power supply rejection (PSRR) of 70 dB, and stability over temperature.
Offered in space-saving 4-bump ultra-thin DSBGA lead-free packages, the LMV1032URX-25 is well-suited for the form factor of miniature electret microphone packages. These packages utilize Large Dome Bump (LDB) technology, designed for microphone PCBs requiring 1 kg adhesion criteria. The typical output voltage noise is -89 dBV, with a signal-to-noise ratio of 61 dB. The operating temperature range is -40°C to 85°C.
