ICS-52000

Microphones Overview

The ICS-52000 is a low-noise digital MEMS microphone featuring a bottom-port design and TDM output. It integrates a MEMS sensor, signal conditioning, ADC, decimation filters, power management, and a 24-bit TDM interface within a 4mm x 3mm x 1mm SMT package. Key electrical parameters include a 65 dBA SNR, -26 dB FS sensitivity with ±1 dB tolerance, and a wide frequency response from 50 Hz to 20 kHz. It operates on a supply voltage of 1.62 V to 3.63 V with a typical current consumption of 1.0 mA. The device supports arrays of up to 16 synchronously sampled channels and offers high power supply rejection of -89 dBFS.

Microphones Procurement Notes

Verify the specific ordering suffix required for your packaging needs, such as tape and reel or cut tape options. Confirm that the component status aligns with your production timeline, noting potential end-of-life notifications. Ensure compatibility with your system's digital processor interface requirements for TDM synchronization. Validate that the 4mm x 3mm footprint fits your PCB layout constraints. Check for any specific RoHS or WEEE compliance documentation if required for your region.

Microphones Selection Notes

Select this component when designing microphone arrays requiring synchronous sampling without an intermediate audio codec. The ±1 dB sensitivity tolerance simplifies calibration efforts in multi-microphone setups. Consider the 1.0 mA current consumption for battery-powered applications. The bottom-port design may influence acoustic enclosure engineering compared to top-port alternatives. Ensure the host processor supports the standard 24-bit TDM protocol for direct integration.
