Audio Subsystem with Mono Class D
Speaker and Class H Headphone Amplifiers
ELECTRICAL CHARACTERISTICS (continued)
(V
HPRVOL = SPKVOL = 0dB, speaker loads (ZSPK) connected between OUTP and OUTN. Headphone loads (RHP) connected from
HPL or HPR to GND. SDA and SCL pullup voltage = 1.8V. ZSPK = J, RHP = J. C
