Note*
Note* = This circuitry is intended for applications where the
CS4344/5/8 connects directly to an unbalanced output of
the design. For internal routing applications please see the
DAC analog output characteristics for loading limitations.
For best 20 kHz response
µF *10
*Popguard ramp can be adjusted by
selecting this capacitor value to be
3.3 µF to give 250 ms ramp time
or 10 µF to give a 420 ms ramp
time.
