ICS-52000 Microphone with TDM Digital Output

TDK InvenSense ICS‐52000 is a low-noise digital TDM output bottom port microphone in a small 4mm × 3mm × 1mm surface‐mount package. The device consists of a MEMS sensor, signal conditioning, an analog‐to‐digital converter, decimation and anti‐aliasing filters, power management, and an industry standard 24‐bit TDM interface. The TDM interface allows an array of up to 16 of the ICS‐52000 microphones to connect directly to digital processors, such as DSPs and microcontrollers, without the need for an audio codec in the system. All microphones in an array sample their acoustic signals synchronously, enabling precise array processing.
