SPH0644LM4H-1CORNELL MULTIMODE DIGITAL BOTTOM PORT SISONICTM MICROPHONE The SPH0644LM4H-1 is a miniature, high-performance, low power, bottom port silicon digital microphone with a single bit PDM output. Using Knowles’ proven high performance SiSonicTM MEMS technology, the SPH0644LM4H-1 consists of an acoustic sensor, a low noise input buffer, and a sigma-delta modulator. These devices are suitable for applications such as cellphones, smart phones, laptop computers, sensors, digital still cameras, portable music recorders, P R O D U C T F E AT U R E S and other portable electronic devices where excellent wideband • Low Distortion /High AOP audio performance and RF immunity are required. In addition, the • High SNR SPH0644LM4H-1 offers multiple performance modes. • Low Current Consumption in Low-Power Mode • Flat Frequency Response Change Vdd Pump Regulator • High Drive Capability Control SELECT • RF Shielded CLK • Bottom Port MEMS Transducer Buffer Σ∆ADC DATA • Sensitivity Matching GND • Supports Dual Multiplexed Channels • Multiple Performance Modes (Sleep, Low-Power, Normal) • Ultra-Stable Performance ABSOLUTE MAXIMUM RATINGS • Standard SMD Reflow • Omnidirectional Table 1: Absolute Maximum Ratings • LGA Package Parameter Absolute Maximum Rating Units T Y P I C A L A P P L I C AT I O N S Vdd, DATA to Ground -0.3, +5.0 V • Portable electronics • Cellphones CLOCK, SELECT to Ground -0.3, +5.0 V • Laptop Computers Input Current ±5 mA • Tablets Short Circuit to/from DATA Indefinite to Ground or Vdd sec • Digital Still Cameras • Portable Music Recorders Temperature -40 to +100 °C Stresses exceeding these “Absolute Maximum Ratings” may cause permanent damage to the device.
