Stereo Audio DAC with  
DirectDrive Headphone Amplifier  
REVISION A ERRATA  
The errata listed below describe situations where the MAX9850 components perform differently than expected or dif-  
ferently than described in the data sheet (this Errata corresponds to Rev 1 of the MAX9850 data sheet). This errata  
sheet applies to all MAX9850 devices until further notice.  
Description:

The MAX9850 data sheet states that the digital audio interface can operate in I S mode in addition to  
left/right justified. After careful observation of actual part operation, it was found that data formatted using  
2
the I S standard cannot be properly decoded by the MAX9850.

I S is a "catch-all" term used to generically describe many digital audio interfaces. In reality, I S is one of many  
2
digital audio formats that can be used to send digital audio data to a decoder. I S is very similar to a mode  
Maxim calls "Left Justified." See Figures 1 and 2.  
Figure 1 shows digital audio data left justified. This audio format is identified by the MSB of the data word on  
SDIN coinciding with the first BCLK transition after LRCLK changes state. Figure 1 shows left- and right-channel  
data both with the SDIN MSB being clocked in on the first BCLK rising edge after the LRCLK transition.
