For analog output, RCA connector: J15 (LOUT1), J28 (ROUT1), J16 (LOUT2), J18 (ROUT2), J17(LOUT3),
J27(ROUT3) are available to use.
Analog outputs are single-ended and output ranges of each channel are nominally 5.6Vpp@5V.
Output range: AOUT is proportional to AVDD2 (AOUT=2 x AVDD2/5 x 1.4 x 2 = 2 x 5/5 x 1.4 x 2 =5.6Vpp).
