Introduction

The SPH21C3LR5H-1 is a bottom-port silicon microphone featuring high SNR and high AOP. Leveraging Knowles' proven high-performance SiSonic MEMS technology, the SPH21C3LR5H-1 consists of an acoustic sensor, a low-noise input buffer, and a differential output amplifier. The microphone's high SNR enhances the user experience in hearable products through transparency mode and active noise cancellation. Its combination of high SNR and high AOP delivers a wide dynamic range in a compact form factor for mobile devices and various IoT applications. The microphone's low phase distortion helps improve algorithm performance. Its differential mode configuration provides enhanced immunity to power supply variations and allows for extended microphone PCB traces.

Applications

• Transparent mode OTE and TWS
• ANC mode OTE and TWS
• Far-field voice conferencing speakerphone and mobile devices
