ALC5642-VF
Datasheet
HPO_L/R
The headphone output of ALC5642 is a stereo output with cap-free type headphone amplifier. It does
not need to connect external capacitor and can connect to earphone device directly. The headphone
output source can mix from output mixer (OUTMIX) or DAC by setting MX-45. The front stage of
headphone output has volume control and gain control. The volume range is from +12dB to -46.5dB
with 1.5dB/step by MX-02.
En_l_hp and en_r_hp (MX-63[7/6]) can be used to power on/off Headphone Amplifier, and
pow_hpo_voll and pow_hpo_volr (MX-66[11/10]) can be used to power on/off headphone volume
control. In addition, pow_pump_hp (MX-8E[3]) can be used to power on/off charge pump circuit for
Headphone Amplifier.
MONO_P/N
The mono output is a differential output with Class-AB type amplifier. The mono output source can
be mixed from analog input, OUTVOL and DAC output by setting MX-4C[15:11]. The front stage of
mono output has gain control for attenuation, the gain control is 0dB or -6dB by MX-4C[10].
Line_OUT_L/R
The output type is line type output. The output is a stereo single ended output. The input can be
selected from OUTVOL or DAC output by setting MX-53[15:12]. The front stage of LOUT output
has gain control for attenuation. The gain control is 0dB or -6dB by MX-53[11].
