Production Data

To avoid clipping at speaker supply, SPKVDD1 and SPKVDD2 must be high enough to support the

peak output voltage when using DCGAIN and ACGAIN functions. The peak output voltage is

AVDD*(DCGAIN+ACGAIN)/2.

DCGAIN should normally be set to the same value as ACGAIN.

See "Volume Updates" for more information on volume update bits, zero cross and timeout operation.

See "Class D Speaker Outputs" for more information on class D speaker operation.

OUT3 OUTPUT

The OUT3 pin can drive a 16 or 32 headphone or a line output or be used as a pseudo-ground for

capless headphone drive (see Headphone Output section). It can also drive out a mono mix of left

and right output mixers (See Output Signal Path).
