National LMV1032-06/LMV1032-15/LMV1032-25 handbook
The LMV1032 is an audio amplifier series specifically designed for 3-wire analog electret microphones. It serves as a replacement for JFET preamps, offering significant advantages in battery life applications such as Bluetooth communication links by reducing microphone supply current to 60 pA.
The device operates with fixed voltage gains of 6 dB, 15 dB, and 25 dB across a supply voltage range of 1.7V to 5V. It is packaged in a space-saving 4-bump ultra thin micro SMD lead-free package.
