IM73A135V01音频设备产品的麦克风规格书PDF中文资料

IM73A135V01属于音频设备产品的麦克风。由英飞凌科技股份公司制造生产的IM73A135V01麦克风麦克风是将声音转换成电信号以便存储、传输和/或转播的换能器。范围从大型悬臂式麦克风到常用的小型 MEMS 产品，并且可根据阻抗、额定电压、灵敏度、频率范围、端口位置、整体尺寸和安装类型进行区分。输出接口提供模拟、I2S、PDM 和 TDM 等种类。

描述 Description

The IM73A135V01 is designed for applications which require a microphone with high SNR (low self-noise), low

distortion (high AOP), which is also IP57 robust to dust and water.

Best-in-class Signal to Noise Ratio (SNR) of 73dB(A) enables far field and low volume audio pick-up. The flat

frequency response ( 20Hz low-frequency roll-off) and tight manufacturing tolerance improve the performance

of multi-microphone array applications.

The high performance analog microphone ASIC contains an extremely low noise preamplifier and a high

performance differential output amplifier. Different power modes can be selected in order to suit specific

current consumption requirements.

Each IM73A135V01 microphone is calibrated with an advanced Infineon calibration algorithm, resulting in small

sensitivity tolerances (± 1dB).
