IM69D127数据手册音频设备产品的麦克风规格书PDF

描述 Description

IM69D127 is a digital high performance MEMS microphone based on Infineon’s new Sealed Dual Membrane MEMS technology which delivers high ingress protection (IP57) at a microphone level. Its small size of only 3.60 x 2.50 x 1.00 mm3 makes it a perfect match for compact audio devices, such as TWS earbuds.

特性 Features

• Very-low self-noise / very-high SNR (69dB)
• Selectable power modes for battery critical applications
• Sealed Dual Membrane (SDM) technology with IP57 ingress protection at microphone level
• Small package size (3.6x2.5x1.0mm)
• Very tight part-to-part phase and sensitivity matching (± 1dB)
• Flat frequency response with a low LFRO (low frequency roll-off) of 40Hz
• Very-low group delay (9µs)

应用 Application

• TWS Earbuds
• ANC Headphones
• Laptops & Tablets
• Wearables
