TDK Announces MIPI Standard SoundWire Microphone

January 23, 2020 Tiera Oliver

TDK Corporation introduces the MIPI Standard SoundWire microphone for mobile, IoT and other consumer devices. This multimode microphone provides advanced feature sets with very low power.

The T5808 SoundWire microphone features 66 dBA SNR and 135dB SPL AOP at 650 µA in high quality mode (HQM), and decreases power consumption to 215µA in low power mode (LPM). The T5808 microphone also features concurrent mode (CCM), enabling simultaneous audio streams from HQM and LPM that can transition back and forth without audio glitches.

SoundWire is a standard audio bus that supports multiple audio devices including microphones, speakers, codecs and class D amplifiers. SoundWire integrates audio and control data for up to 11 devices (e.g. 7mics, 4 speakers) on a single bus.

T5808 is currently in mass production and will be available through distribution in Q1 2020.  For samples and additional information, please contact sales@invensense.com or visit www.invensense.tdk.com/products/digital/t5808/
