2.3.2.1 TAx5x42 Analog Audio Output

The EVM analog audio output port provides option for AC/DC-Coupled, filter/filter-less path for easy evaluation. By default the filter components are not populated.

OUT1 and OUT2 audio output pins have connection options with external load or the on-board load selections. A pair of RCA connectors, white from OUTP and red from OUTM allow users to connect to external device either as differential or single ended. Jumper header J36 or J37 needs to be populated if single-ended is desired or removed otherwise for differential configuration.

Switch SW1 allows users to select respective load for each output pair for 16 Ohm, 604 Ohm or 10K Ohm if needed. These resistors are for quick evaluation and can be bypassed for actual load. SW1 and the output RCA connectors are located on the top left hand side shown in co below.

SW1 pin Load Configuration Resistor Rating
1, 4, 7, 10 16 Ohm 0.5 W
2, 5, 8, 11 604 Ohm 0.125 W
3, 6, 9, 12 10 KOhm 0.4 W

For TAA5242, OUT1 and OUT2 components are not populated.
