IMP34DT05 : The IMP34DT05 is an ultra-compact, low-power, omnidirectional, digital MEMS microphone built with a capacitive sensing element and an IC interface. The sensing element, capable of detecting acoustic waves, is manufactured using a specialized silicon micromachining process dedicated to producing audio sensors. The IC interface is manufactured using a CMOS process that allows designing a dedicated circuit able to provide a digital signal externally in PDM format. The IMP34DT05 is a low-distortion digital microphone with a 64 dB signal-to-noise ratio and –26 dBFS ±3 dB sensitivity. The IMP34DT05 is available in a top-port, SMD-compliant, EMI-shielded package and is guaranteed to operate over an.

IMP3522D : The IMP3522D(S) is a complete adaptive ballast controller, 450V half-bridge driver and power MOS FET integrated into a single IC for Compact Fluorescent Lamps (CFL) applications. The IC includes adaptive zero-voltage switching (ZVS), internal crest factor over-current protection, as well as an integrated bootstrap FET. The heart of this IC is a voltage controlled oscillator with externally programmable minimum frequency. All of the necessary ballast features are integrated in a small 8-pin DIP package. Key Features -450V Half Bridge Driver -Integrated Bootstrap FET -Integrated Power MOS FET -Adaptive zero-voltage switching (ZVS) -Internal Crest Factor Over-Current Protection -0 to 6VDC Volt.
