SPH1611LR5F

Overview

The SPH1611LR5F is a digital MEMS microphone manufactured by Syntiant. It features a bottom-port acoustic design and utilizes Pulse Density Modulation (PDM) for digital audio output. The device operates on a single 1.8V supply voltage. Key electrical specifications include a signal-to-noise ratio of 64dB, a maximum sound pressure level of 120dB SPL, and a sensitivity of -26 +/-1dBV. The frequency response begins at 45Hz, and the unit offers a power supply rejection ratio of 55dB. Power consumption is specified at 235µA in low-power mode and 620µA in standard mode.

Procurement Notes

Verify the specific suffix 'LR5F' against official Syntiant documentation to confirm package type and tape-and-reel specifications. Ensure the required operating voltage aligns with the 1.8V specification. Confirm RoHS compliance status through the manufacturer's current datasheet before finalizing procurement plans.

Selection Notes

Select this component when a digital MEMS microphone with bottom-port geometry is required for compact designs. Consider the 64dB SNR and 120dB SPL limits for appropriate acoustic environments. Evaluate the 1.8V supply requirement against the system's available power rails. Compare power consumption modes against battery life requirements.

Part Context

This part belongs to the SISONIC series of MEMS microphones produced by Syntiant. These components are designed for high-performance audio capture in consumer electronics. The series integrates acoustic sensing with digital signal processing interfaces.
