November 2011
January 2012
Corrected the I/O type for the Analog output pins. Corrected the pin location in Analog output pin
table for the BTL outputs.

September 2012
October 2012
Clarifications to MCLK rate. Updated PLL Electrical characteristics.
Corrected HP_L and HP_R pin location in pin table to match the pin diagram.
Removed typical and low power consumption tables from electricals section, since these metrics are
driven by software settings and are system specific, the typicals listed were not representative of
what can be expected of the device.
