ICS‐52000 Product Brief
Low‐Noise Microphone with TDM Digital Output
GENERAL DESCRIPTION
The ICS‐52000 is a digital TDM output bottom port microphone.
The complete ICS‐52000 solution 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.
The ICS‐52000 has a high SNR of 65 dBA and a wideband
frequency response. The sensitivity tolerance of the ICS‐52000
is ±1 dB, which enables high‐performance microphone arrays
without the need for system calibration.
The ICS‐52000 is available in a small 4 mm × 3 mm × 1 mm
surface‐mount package.
