CS42L56
ANALOG OUTPUT ATTENUATION CHARACTERISTICS
Test Conditions (unless otherwise specified): Connections to the CS42L56 are shown in the “Typical Connection Diagrams” on
page 11; GND = AGND = 0 V. Attenuation is referenced to the full-scale voltage for the given output. Test load R
L
= 3 k
C
L
= 150 pFfor a line load, and test load R
L
=16 C
L
= 150 pF for a headphone load (See Figure 6 and Figure 7 on page 21).
Notes:
26. Assumes no external impedance on HPREF or LINEREF. External impedance on HPREF or LINEREF
will impact the attenuation.
