Need info on WS polarity for TDA1541

peufeu · 17th October 2006, 02:57 PM

Simple question :

Does the DAC send the digital data to the analog outputs...

- On the rising edge of WS/LE ?
- On the falling edge of WS/LE ?

Also I would use the "simultaneous inputs" mode with both L&R channels input simultaneously and stopping the bit clock before toggling the Latch Enable.

I just need to know which way to toggle it

I wanted to be sure the i2s encoder I wrote would work with this chip since I have one laying around somewhere
