TDK announces world’s first MIPI standard SoundWire microphone

TDK Corporation introduces the world’s first MIPI Standard SoundWire® microphone for mobile, IoT and other consumer devices. This multimode microphone pushes the boundaries of digital microphone acoustic performance while providing advanced feature sets with very low power.

Highlights

• T5808 is a 66 dB SNR/135 dB AOP digital microphone in a 3.5 × 2.65 × 0.98 mm package
• Supports up to seven individually configurable microphones on a single audio bus
• SoundWire 1.1 compliant based on Mobile Industry Processor Interface (MIPI) Alliance open standards

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

Key features

• 5 × 2.65 × 0.98 mm surface-mount package
• Low power: 215 µA in Low-Power Mode
• Extended frequency response from 40 Hz to >20 kHz
• Sleep Mode: 10 µA
• High power supply rejection (PSR): −91 dB FS
• Fourth-order Σ-Δ modulator
• Digital pulse density modulation (PDM) output
• Compatible with Sn/Pb and Pb-free solder processes
• RoHS/WEEE compliant

The SoundWire Standards Committee, who created the MIPI standard for SoundWire, includes technology leaders in application processors, audio DSPs and codecs, and other ICs. SoundWire is a standard audio bus that supports multiple audio devices including microphones, speakers, codecs and class D amplifiers. SoundWire revolutionizes how audio devices and ICs communicate by integrating audio and control data for up to 11 devices (e.g. 7 mics, 4 speakers) on a single bus.
