ANALOGUE OUTPUTS The WM8985 has three sets of stereo analogue outputs. These are: • LOUT1 and ROUT1 which are normally used to drive a headphone load. • LOUT2 and ROUT2 – which can be used as class D or class AB headphone drivers. • OUT3 and OUT4 – can be configured as a stereo line out (OUT3 is left output and OUT4 is right output) or a differential output. OUT4 can also be used to provide a mono mix of left and right channels. The outputs LOUT2 and ROUT2 are powered from AVDD2 and are capable of driving a 1V rms signal (AVDD1/3.3). LOUT1, ROUT1, OUT3 and OUT4 are powered from AVDD1 LOUT1, ROUT1, LOUT2 and ROUT2 have individual analogue volume PGAs with -57dB to +6dB gain ranges. There are four output mixers in the output signal path, the left and right channel mixers which control the signals to headphone (and optionally the line outputs) and also dedicated OUT3 and OUT4 mixers. |
