I know it does not fit the wanting BGA part, but
if you really want a Digital Microphone take a look
at http://www.akustica.com/ who really sells
true Digital Microphones.

"Akustica's digital microphones are the world's first surface mountable
monolithic digital microphone chips that integrate an acoustic transducer,
 analog output amplifier, and sigma-delta modulator on a single chip. 
The single-bit digital output stream connects to downstream electronics 
without shielded cabling or complex signal routing, providing the highest 
degree of design flexibility and freedom. Acoustic performance of
Akustica digital microphone chips is equal to or better than conventional analog microphones. 

An important benefit of Akustica digital microphones is their immunity to 
RF (radio frequency) and EM (electromagnetic) interference, which allows 
placement in optimal acoustic locations regardless of proximity to displays, 
WiFi antennae or other sources of interference that would degrade or
 preclude use of conventional microphones."

They charge far to much for their evaluation kits...
