The TAx541x-Q1 evaluation module has several output configuration options and offers flexibility to allow the user to evaluate the device with different load conditions and configurations. The different configurations are highlighted in this section.
The EVM analog audio output port provides option for AC/DC-Coupled and filter or filter-less paths for easy evaluation. By default the filter conponents are not populated.
Switch SW1 allows users to select respective loads 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 Figure 3-11.
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 as differential or single ended. Jumper header J36 or J37 must be populated if single-ended is desired or removed otherwise for differential configuration.
SW1 pin | Load Configuration | Resistor Rating | Output Module Register Setting |
---|---|---|---|
1, 4, 7, 10 | 16 Ω | 0.5 W | B0_P0_R101 |
2, 5, 8, 11 | 604 Ω | 0.125 W | B0_P0_R101 |
3, 6, 9, 12 | 10 kΩ | 0.4 W | B0_P0_R101 |
For TAC5x11-Q1, OUT2 components are not populated.
