Embedded digital MEMS microphone for laptop Akustica

The AKU2001 is a surface-mountable, digital-output silicon microphone with a tri-state output, allowing the outputs of two microphones to be multiplexed together and share a single data line. The AKU2001 integrates an acoustic transducer and a 4th-order sigma-delta modulator on a single chip. The output of the AKU2001 is Pulse Density Modulated (PDM), or a single-bit digital output stream that can be decimated by a digital filter in downstream electronics such as an audio CODEC, DSP, or base band processor.

BENEFITS OF THE AKU2001

- Digital-output microphone designed specifically for optimal performance and design simplicity of microphone arrays
- Ideal for use with Microsoft Vista™ audio applications
- Surface-mountable and automated pick & place compatible
- Robust digital-output immune to RF and EM interference enabling increased audio design flexibility while reducing design complexity
- Tri-state output reduces number of wires required
- Shielded cabling not required
- PSR eliminates the need for a regulated power supply
- Small form factor enables placement in thin profile areas
