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 pF

for 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.
