getting the most of out ak4396

[PreSapian]

it's my short knowledge that ak4396 has an internal digital volume control and a slow roll off filter. i'd like to know how to utilize them so that i can connect the dac directly to my amp without the need for a pot, and also it's been my experience that slow roll off usually sounds better.

thanks in advance.

To adjust the internal digital volume, you look to need an external micro that either has an SPI-style serial interface or can 'big-bang' the clock and data pins in software. The same serial interface selects the type of digital filter - after reset the chip uses the sharp roll-off.
