TDK CORPORATION - New T5828 is a MIPI SoundWire™ compliant MEMS microphone
- Offers 68dBA SNR and Acoustic Activity Detect features with always-on ultra-low power mode
January 6, 2022
TDK Corporation (TSE: 6762) introduces the T5828 SoundWire™ MEMS microphone as part of the SmartSound™ family of performance products for mobile, TWS, IoT and other consumer devices. This family of high-performance microphones pushes the boundaries of microphone acoustic performance, providing advanced feature sets in small package footprints. The T5828 SoundWire™ MEMS microphone offers a high acoustic overload point (AOP) of 133dB SPL, high signal-to-noise ratio (SNR) 68dBA and wide dynamic range, ideal for environments that shift from very quiet to very loud.
The T5828 microphone:
- Offers very low power, wide dynamic range SoundWire™ Digital
- Introduces Acoustic Activity Detect (AAD) to a SoundWire™ microphone for the first time allowing easy configuration within the SoundWire control protocol, including a very low power 20uA general purpose activity detection to a highly configurable voice activity detection feature.
- Institutes new submodes within the existing High Quality and Low-Power modes allowing dynamic customization of mic performance including:
- Enhanced AOP mode, 136dB SPL
- Ultra-Low Power mode, 95uA (the first
"TDK continues to expand the SoundWire™ ecosystem by introducing T5828, the most advanced SoundWire™ MEMS microphone available today," said Ritesh Tyagi, Vice President of Product Management at InvenSense, a TDK group company. "In partnership with Qualcomm, we are demonstrating the advantages of SoundWire™ allowing a simple two wire interface for up to eleven audio devices, a bi-directional audio data stream, and a superior control interface compared to other digital interfaces."
The TDK T5828 has a small 3.5 x 2.65 x 0.98 mm bottom port package and is available for sampling.
