MP23DB01HP MEMS audio sensor: digital microphone with multiple performance modes
●Description
■The MP23DB01HP is an ultra-compact, low-power, omnidirectional, digital MEMS microphone built with a capacitive sensing element and an IC interface with stereo operation capability. The sensing element, capable of detecting acoustic waves, is manufactured using a specialized silicon micromachining process dedicated to producing audio sensors.
■The IC interface is manufactured using a CMOS process that allows designing a dedicated circuit able to provide a digital signal externally in PDM format.
■The MP23DB01HP offers multiple performance modes (power-down, low-power and performance mode) enabled by different clock frequency ranges.
■The device has a very high AOP in performance mode, sensitivity range of ±1 dB and high SNR for all operative modes.
■The MP23DB01HP is available in a bottom-port, SMD-compliant, EMI-shielded package and is guaranteed to operate over an extended temperature range from -40 °C to +85 °C.
