A number of years ago we sold our analog MEMS microphone products to Invensense. You can find them here:
I do not think you will find what you are looking for. First, the analog outputs are single ended and you will need a differential output to go to an XLR. Then the drive strength will not be sufficient to drive a mic cable any distance. So some sort of amplifier will be required and some sort of power supply to take the phantom power and regulate it down to the proper voltage. So this can all be done but I do not think anyone has a produce ready to go but I certainly could be wrong. I have not searched the web for the solution.
A part you might want to look into is the SSM6322. It is an amplifier meant for headphones which might work for you. Not certain, you will have to investigate this further but it is an interesting new product we came out with.
