ICS-52000 Low-Noise Microphone with TDM Digital Output GENERAL DESCRIPTION APPLICATIONS Speech Recognition Arrays The ICS-52000 is a digital TDM output bottom port microphone. Smart Televisions The complete ICS-52000 solution consists of a MEMS sensor, signal Teleconferencing Systems conditioning, an analog-to-digital converter, decimation and anti- Gaming Consoles aliasing filters, power management, and an industry standard 24- Security Systems bit TDM interface. The TDM interface allows an array of up to 16 of Microphone Arrays the ICS-52000 microphones to connect directly to digital processors, such as DSPs and microcontrollers, without the need FEATURES for an audio codec in the system. All microphones in an array Digital TDM Interface with High Precision 24-bit Data sample their acoustic signals synchronously, enabling precise array Supports TDM arrays of up to 16 synchronously- processing. sampled channels High 65 dBA SNR The ICS-52000 has a high SNR of 65 dBA and a wideband frequency 26 dB FS Sensitivity response. The sensitivity tolerance of the ICS-52000 is 1 dB, 1 dB Sensitivity Tolerance which enables high-performance microphone arrays without Wide Frequency Response from 50 Hz to 20 kHz the need for system calibration. Low Current Consumption: 1.0 mA The ICS-52000 is available in a small 4 mm 3 mm 1 mm High Power Supply Rejection: 89 dB FS surface-mount package. 117 dB SPL Acoustic Overload Point Small 4 mm 3 mm 1 mm Surface-Mount Package Compatible with Sn/Pb and Pb-Free Solder Processes RoHS/WEEE Compliant FUNCTIONAL BLOCK DIAGRAM ORDERING INFORMATION PART TEMP RANGE PACKAGING ICS-52000 ICS-52000 40C to +85C 13 Tape & Reel FILTER ADC SCK EV ICS-52000-FX TDM SD SERIAL PORT WS POWER HARDWARE MANAGEMENT CONTROL WSO InvenSense Inc.
