The complete INMP441 solution consists of a MEMS sensor, signal conditioning, an analog-to-digital converter, anti-aliasing filters, power management, and an industry-standard 24-bit IS interface. The IS interface allows the INMP441 to connect directly to digital processors, such as DSPs and microcontrollers, without the need for an audio codec in the system. The INMP441 has a high SNR, making it an excellent choice for near field applications. The INMP441 has a flat wideband frequency response, resulting in natural sound with high intelligibility. The INMP441 is available in a thin 4.72 x 3.76 x 1 mm surface mount package. It is reflow- solder compatible with no sensitivity degradation. The INMP441 is halide free. Applications: Teleconferencing Systems Remote Controls Gaming Consoles Mobile Devices Laptops Tablets Security Systems Feature: Digital IS Interface with High-Precision 24-Bit Data High SNR of 61 dBA High Sensitivity of -26 dBFS Flat Frequency Response from 60 Hz to 15 kHz Low Current Consumption of 1.4 mA High PSR of -75 dBFS Small 4.72 x 3.76 x 1 mm Surface-Mount Package Compatible with Sn/Pb and Pb-Free Solder Processes RoHS/WEEE Compliant Package includes: 1 x Microphone module
