These advanced mixed signal preamplifiers cleanly, accurately and creatively eliminate older, poorer quality systems, which restricted performance and versatility. The 4-wire PDM signaling reduces RF noise and simplifies layout. Using National's PDM solutions is the choice for higher quality mono or stereo and multi-array applications. National's 518uA circuits deliver stereo portability with audio quality bandwidth. These solutions enable rapid system evaluation and enhance consumer satisfaction. National provides the LMV1024 and LMV1026 in 6-bump micro SMD packages with 1 kg adhesion properties.
