CS42L73
DC ELECTRICAL CHARACTERISTICS
Test Conditions: Connections to the CS42L73 are shown in the “Typical Connection Diagram” on page 17 ; GND = AGND =
PGND = CPGND = DGND = 0 V; all voltages are with respect to ground (GND); VA = VCP = 1.80 V, VP = 3.70 V; T
A
= +25 C.
Notes:
8. No load (from specification tables “Serial Port to Stereo HP Output Characteristics” on page 27 and “Serial Port to Ste-
reo Line Output Characteristics” on page 29 , R
L
=  and C
L
= 0 pF) connected to Headphone and Line Outputs
(HPOUTx and LINEOUTx). Headphone Zobel Network remains connected.
9. See “Analog Output Current Limiter” on page 51 .
