Infineon Technologies XENSIV™ MEMS-mikrofoner

Mikrofonerna har dubbla bakstycken i MEMS-teknik, baserat på en miniatyriserad symmetrisk mikrofondesign, som används i kondensatormikrofoner för studiobruk. Detta resulterar i en hög linjär utsignal inom ett dynamiskt område på 95 dB för IM69D120 och 105 dB för IM69D130. Detta kombineras med en exceptionellt låg distorsionsnivå på 10 procent vid ljudtrycksnivå på 135 dB (SPL).

IM69D128S

Great signal-to-noise ratio (SNR) of 69dB(A) enables a crystal clear audio experience without compromising on battery life. Enabled by a revolutionary digital microphone ASIC, the IM69D128S sets a benchmark by cutting current consumption to 520μA – almost half of what models with similar performance on the market can offer.  Additionally, IM69D128S masters the art of switching between different power and performance profiles without any audible artifacts, i.e., glitches that the user can hear.
