INMP441 Omnidirectional MEMS Microphone Module 6-Pack, I2S Interface, Low Power, High Precision, ESP32 Compatible

INMP441 Omnidirectional MEMS Microphone Module 6-Pack, I2S Interface, Low Power, High Precision, ESP32 Compatible Description

The INMP441 is a high performance, low power, digital output, omnidirectional MEMS microphone with bottom port.
The complete INMP441 solution consists of a MEMS sensor, signal conditioning, an analog-to-digital converter, an anti-aliasing filter, power management, and an industry standard 24-bit I2S interface.
The I2S interface allows the INMP441 to be connected directly to digital processors such as DSPs and microcontrollers without the need for an audio codec for use in the system.
Key advantages and suitability:
- Direct digital path reduces design time and BOM by removing the need for an external codec.
- Omnidirectional pickup and bottom port design enable consistent sound capture.
- 24-bit I2S interface provides high resolution audio and easy integration with DSPs and MCUs.
- Low power operation supports battery-powered and portable devices.
Key attributes:
- Function: digital omnidirectional MEMS microphone with bottom port.
- Interface: industry standard 24-bit I2S.
- Compatibility: works with DSPs and microcontrollers without external codecs.
- Material: MEMS sensor package.
- Performance: high performance with low power.
Applications and use cases:
- Voice input for embedded DSP/microcontroller systems and voice-enabled products.
- Speech-enabled smart home and IoT devices requiring digital audio capture.
- Portable recorders and handheld devices needing high‑quality digital audio without an external codec.
