When RCV bit = “1”, LOUT/ROUT pins become RCP/RCN pins, respectively. Lch/Rch signal of DAC or
LIN2/RIN2/LIN3/RIN3 is output from the RCP/RCN pins which is BTL as (L+R)/2 signal. The load impedance is 32
(min). When the PMLO bit = “0”, the mono receiver output enters power-down mode and the output is Hi-Z. When the
PMLO bit is “1” and LOPS bit is “1”, mono receiver output enters power-save mode. Pop noise at power-up/down can be
reduced by changing PMLO bit at LOPS bit = “0”. When PMLO bit = “1” and LOPS bit = “0”, mono receiver output
enters in normal operation. LOVL bit set the gain of mono receiver output.
