David Jones talks about Infineon's XENSIV MEMS microphones that could be used in a range of products from active-noise-cancellation (ANC) headphones to security systems that can detect glass breaking.

The new microphones include the IM69D127, IM73A135, and IM72D128. The IM73A135 is an analog microphone that features best-in-class signal-to-noise ratio (SNR) of 73 dB(A) with an acoustic overload point (AOP) of 135 dB SPL (sound pressure level). The IM72D128 is its digital counterpart. The digital device delivers an SNR of 72 dB(A) and an AOP of 128 dB SPL. IM69D127 features similar performance but in a tiny 3.6- × 2.5-mm package..

I earned a Bachelor of Electrical Engineering at the Georgia Institute of Technology and a Masters in Computer Science from Rutgers University. I still do a bit of programming using everything from C and C++ to Rust and Ada/SPARK. I do a bit of PHP programming for Drupal websites. I have posted a few Drupal modules.

I still get a hand on software and electronic hardware. Some of this can be found on our Kit Close-Up video series. You can also see me on many of our TechXchange Talk videos. I am interested in a range of projects from robotics to artificial intelligence.
