The TDK T5919, T3903 and T4086 MEMS microphones are part of a fully compatible and multi-grade SmartSound portfolio of microphone products from TDK InvenSense. Each of these new MEMS microphones pushes the boundaries of microphone acoustic performance, providing advanced feature sets with very low power in small package footprints. All models are compatible with Sn/Pb and Pb-free solder processes, and are RoHS/WEEE compliant.
The SmartSound family of MEMS microphones from TDK are designed for a multitude of applications in a variety of dynamic environments. All models offer high acoustic overload point (AOP), high SNR and wide dynamic range and are ideal for environments that shift from very quiet to very loud, such as far field voice pickup barge-in for Smart Speaker applications.
The new T5919 is the world’s first PDM digital output microphone with built-in Particle Ingress Filter (PIF). This is a multi-mode, low noise digital MEMS microphone in a small 3.5 × 2.65 × 0.98mm bottom port package. The PIF filter is embedded in the microphone package, providing protection to particles and moisture. The T5919 supports multiple modes of operation, from High Quality, to Low-Power (AlwaysOn), and Sleep, while maintaining high SNR in all operational modes. The microphone maintains 135dB SPL AOP in High Quality Mode and 120dB SPL AOP in Low-Power mode.
The new T4086 model is an ultra-small analog output MEMS microphone, designed to achieve high SNR and AOP at low power in a tiny 2.75 × 1.85 × 0.9mm bottom port package to support very space constrained applications/devices.
The new T3903 is a very low power wide dynamic range PDM MEMS microphone, enabling the transition of microphones from analog output to digital output to support ‘AlwaysOn’ applications in smartphones, tablets, remote controls, smart TVs, Bluetooth headsets and earbuds, and digital still/video cameras. The T3903 is a multi-mode, low noise, bottom ported MEMS microphone with -37dBFS sensitivity, 66dBA SNR and 133dB AOP in a 3.5 × 2.65 × 0.98mm package.
"TDK continues its commitment to bringing to market a broad portfolio of disruptive, high performance and innovative SmartSound solutions,” says Omar Abed, GM and VP of microphone business unit at InvenSense, a TDK group company. “By applying several new MEMS technological breakthroughs, we developed microphones designed for a multitude of applications in a variety of challenging and dynamic environments, thus enabling our customers to create a differentiated audio experience.”
InvenSense, a TDK Group company, specializes in MEMS sensor platforms for consumer electronics and industrial applications. InvenSense’s solutions include accelerometers, gyroscopes, compasses, and microphones with proprietary algorithms and firmware that intelligently process, synthesize, and calibrate the output of sensors, maximizing performance and accuracy. In May of 2017, InvenSense became part of the MEMS Sensors Business Group within the newly formed Sensor Systems Business Company of TDK Corporation.
