Hi,I'm using an MP23DB02MM digital mic on the CCA02M2 eval board and using the PDM2PCM library. When I have no sound into the microphone the noise floor I see in the data from the PDM2PCM output is around 1,000 counts peak to peak noise. I'm struggli...
I interested in the higher frequency range of this device. The datasheet states clearly the LF cutoff at 35Hz, but there is no real discussion on the HF end apart from the characteristic graphs stopping at 10KHz. The device can be clocked up to 3.3MH...
Does anybody know if there is any difference between these two MEMS Microphones. The IMP23ABSU does have some Ultrasonic characteristics, but my understanding is the MEMS mics would have ultrasonic bandwidth anyway.Thanks
Hi,Looking at the PM8805 PoE Controller datasheet fig 7 and also AN5207 page 30 there is a 3M3 resistor from power ground to chassis ground. What it purpose, is this some form of bleed resistor to stop voltage build up? My main question though is why...
I'm looking to use a PM8804 along with PM8805 to produce a 24V, 2.5A POE PD. Are there any application notes available on how to design and calculate components for a forward active clamp converter similar to the schematic in the datasheet. I've look...
