Description
Key points:
- Digital output: PDM stream requiring a clock and host-side decimation/filtering to PCM.
- Small, low-profile package suitable for compact boards.
- Supply and interface conform to typical MEMS mic ranges; exact voltages and timing are in the datasheet.
- Used for voice input in smartphones, laptops, wearables, conferencing devices, and smart assistants.
For precise electrical specs, pinout, clock requirements, and performance (SNR, sensitivity, power), refer to the official MP34DB02TR datasheet.
Equivalent
- InvenSense ICS-43434
- Knowles SPH0645LM4H-B
- STMicroelectronics MP45DT02
- STMicroelectronics MP34DT05
These offer similar PDM digital MEMS mic functionality; verify packaging (TR) and electrical specs for exact compatibility.
Features
- Bottom-port MEMS microphone
- Digital PDM output (Dout) with external clock (CLK) input
- Omnidirectional audio pickup
- Low-noise, high-SNR performance for clear voice
- Wide dynamic range suitable for speech and general audio
- Low power consumption during operation
- Small package size with Tape & Reel (TR) packaging for automated assembly
- Wide supply voltage range (typical 1.65–3.6 V)
- Compact form factor suitable for compact consumer devices
Note: For exact electrical specs (SNR, sensitivity, frequency response, current, clock) and recommended operating conditions, please refer to the official datasheet.
Pinout
- VDD: power supply
- GND: ground
- CLK: PDM clock input
- DOUT: PDM data output
- L/R: left/right channel select
