CS7250B

CS7250B Digital MEMS Microphone with High Performance and Low Power Modes Features High acoustic overload point (AOP, 131 dB SPL) High signal-to-noise ratio (SNR, 66 dB) Low variation in sensitivity (±1 dB) Low current consumption — 650 A (High Performance Mode) — 160 A (Low Power Mode) — 5 A (Standby Mode) PDM digital audio output Bottom-port LGA package 1.8-V supply Description The CS7250B is a high-performance digital MEMS microphone, offering class-leading total harmonic distortion (THD) performance, excellent SNR, and low power consumption. The CS7250B supports two operational modes, selected according to the applied clock frequency. Low Power Mode is ideal for always-on voice activity detection; High Performance Mode is optimized for high fidelity recording. The CS7250B incorporates a high-performance ADC, which outputs a single-bit data stream using pulse density modulation (PDM) encoding. The CS7250B supports selectable left/right ...
