InvenSense said it has started sampling its ICS-40720 analogue MEMS microphone among select clients. The ICS?40720 is an RF?hardened, low-noise, low-power, differential analogue output MEMS microphone that includes a new MEMS sensor and a low-noise signal conditioning amplifier. The product is intended for consumer electronic devices such as smartphones, tablets, digital still/video cameras, teleconferencing systems, Bluetooth headsets, notebook PCs, and security/surveillance systems.

The company says the ICS?40720 has a high SNR and extended wideband frequency response for improved sound quality and intelligibility. The product has a low current consumption of 160µA and allows long battery life for portable consumer electronic applications. It comes in a 4mm x 3mm x 1.2mm package.

"Achieving 70dB SNR is a technological breakthrough for MEMS based microphones. The InvenSense ICS?40720 is a disruptive product, meeting the market requirement for a human-like interface between people and consumer electronics," said Ali Foughi, Vice President of Marketing and Business Development at InvenSense.
