IA610-2

Microphones Overview

The IA610-2 is a smart microphone from the Syntiant AISonic family, integrating a DSP and bottom-port MEMS sensor in a single package. It operates on a supply voltage of 1.71 V to 1.98 V with a current consumption of 5 mA. The device features an omnidirectional acoustic response with a sensitivity of -37.5dB ±1dB @ 94dB SPL. Digital output interfaces include I2S, PDM, and TDM, supporting clock frequencies from 768 kHz to 200 MHz.

Microphones Feature Summary

• Integrates a 43MHz Tensilica audio-optimized DSP for edge processing within the microphone package
• Provides wake-on-voice capabilities using high-performance SiSonic MEMS technology
• Supports multiple digital output protocols including I2S, PDM, and TDM

Microphones Applications

• Wake-on-voice activation in battery-powered devices

Microphones Procurement Notes

Verify the specific suffix against official Syntiant documentation to confirm interface compatibility and pinout configuration. Ensure the selected variant matches the required digital protocol (I2S, PDM, or TDM) for the target system design. Confirm availability status as product lines may transition between active and obsolete states.

Microphones Selection Notes

Select this component when low-latency, always-on voice detection is required without burdening the main application processor. The integrated DSP allows for efficient power management by filtering audio data locally before transmission. Consider the operating voltage range and digital interface requirements of the host MCU during integration.
