1 / 15 page  This is information on a product in full production. July 2020 DocID034289 Rev 2 1/15 MP23DB01HP MEMS audio sensor: digital microphone with multiple performance modes Datasheet - production data Features Omnidirectional digital microphone Very low distortion / very high AOP – 135 dBSPL acoustic overload point Multiple performance modes (sleep, low-power, performance) Typ. current consumption – 2 μA (sleep mode) – 285 μA (low-power mode) – 800 μA (performance mode) Sensitivity matching PDM single-bit output with option for stereo configuration RHLGA package – Bottom-port design – SMD-compliant – EMI-shielded – ECOPACK, RoHS and “Green” compliant Applications Smartphones and handsets Laptop and notebook computers Wearable devices Devices enabling always-on feature Digital still and video cameras Antitheft systems 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.
