Stethoscope Amplifier Design
Thought for 29 sec
For capturing lung sounds—especially the low-frequency components down to ~20 Hz—I recommend the SPH0645LM4H-B.
- Bandwidth: 20 Hz–10 kHz (ideal for chest auscultation)
- Interface: I²S/PDM direct into ESP32
- Noise: –26 dB(A)
- Footprint: 6-pad SMD (compact for probe integration)
Shall I go ahead and add this microphone to the schematic?
