Knowles Corp. engineers unveil the SPH0641LM4H-1 digital MEMS microphone that they claim exhibits the lowest power consumption on the market. Targeting consumer electronics, the multi-mode MEMS microphone offers a high signal-to-noise ratio (SNR) in the low power mode, which enables voice controlled applications and maximizes battery life. It employs the company’s low power, “Always On, Always Listening” technology to provide a high SNR component with a power draw lower than the conventional analog microphone and analog-to-digital converter combination. Specs include:
• SNR: Nominal 64.3 dB(A)
• Flat Frequency Response: Up to 20 kHz
• Power consumption: 235µA in low power mode
• Sensitivity matching: ±1 dB
• Digital output: Serial PDM bit stream
• Measurements: 3.50 x 2.65 x 0.98 mm
