Receiver-Amp (RCP/RCN pins)
When RCV bit = “1”, LOUT1/ROUT1 pins become RCP/RCN pins, respectively. Lch/Rch signal of DAC or
LIN1/RIN1/LIN2/RIN2/LIN3/RIN3/LIN4/RIN4 is output from the RCP/RCN pins which is BTL as (L+R) signal. The
load impedance is 32
Ω
(min). When the PMLO1 = PMRO1 bits = “0”, the mono receiver output enters power-down
mode and the output is Hi-Z. When the PMLO1 = PMRO1 bits = “1” and LOPS1 bit = “1”, mono receiver output enters
power-save mode. Pop noise at power-up/down can be reduced by changing PMLO1 and PMRO1 bits at LOPS1 bit =
“0”. When PMLO1 = PMRO1 bits = “1” and LOPS1 bit = “0”, mono receiver output enters in normal operation.
L1VL3-0 bits control the volume of mono receiver output.
