Knowles SPH0641LU4H-1 SMD Microphone

The SPH0641LU4H-1 is a miniature, high performance, low power, bottom port silicon digital microphone with a single bit PDM output. Using Knowles’ proven high performance SiSonicTM MEMS technology, the SPH0641LU4H-1 consists of an acoustic sensor, a low noise input buffer, and a sigma-delta modulator. It allows the microphone to assist smartphones and consumer electronics with touch-less gesture recognition, phone-to-phone data transmission, pen input compatibility for handsets and tablets, and 3D positioning input.
