CS42L73

SERIAL PORT TO STEREO HP OUTPUT CHARACTERISTICS

Test conditions (unless otherwise specified):

“Typical Connection Diagram” on page 17

shows CS42L73 connections (including

Zobel Networks on outputs); Input test signal is a 24-bit full-scale 997-Hz sine wave with 1 LSB of triangular PDF dither applied;

GND = AGND = PGND = CPGND = DGND = 0 V; all voltages are with respect to ground (GND); VA = VCP = 1.80 V; T

A

= +25

C; VCP Mode; Measurement Bandwidth is 20 Hz to 20 kHz; Fs = 48 kHz

(Note 10)

; ASP is used and is in slave mode with Fs

ext

= 48 kHz; test loading is configured as per
