7.3.1.5 Output Channel Configurations

The device consists of two pairs of analog output pins (OUTxP and OUTxM) that can be configured as differential inputs or single-ended outputs for playback channel. The device supports simultaneous playback of up to four channels single-ended output or up to two channel differential output using the high-performance multichannel DAC. Table 7-8 shows the input source selection for the playback channels.

Table 7-8 Input Source Selection for the Playback Channel
P0_R100_D[7:5] : OUT1x_SRC[2:0]OUT1P/OUT1M Source Selection
000 (default)Output driver disabled
001DAC signal chain
010Analog bypass signal chain
011Mixing of DAC and analog bypass signal chains
100OUT1P for DAC and OUT1M for analog bypass signal chain
101OUT1P for analog bypass and OUT1M for DAC signal chain.
11xReserved. Do not use this setting.

Similarly, the input source selection setting for output channel 2 can be configured using the OUT2x_SRC[2:0] (P0_R107_D[7:5]) register bits.

The TAD5112 supports up to 2 channel differential output, up to 2 channel pseudo-differential output and up to 4 channel single-ended output. Each of the output channels can be independently configured for differential or single-ended output.

Table 7-9 shows the configuration modes for the output pins

Table 7-9 Output Pin Configuration for the Playback Channel
P0_R100_D[4:2] : OUT1x_CFG[2:0]OUT1P/OUT1M Pin Configuration
000 (default)OUT1P/OUT1M as a differential pair
001OUT1P and OUT1M as independent single-ended outputs
010Mono Single Ended output on OUT1P only
011Mono Single Ended output on OUT1M only
100Pseudo differential output with OUT1P as signal and OUT1M as VCOM
101Pseudo differential output with OUT1P as signal, OUT1M as VCOM and OUT2M as VCOM sense.
110Pseudo differential output with OUT1M as signal and OUT1P as VCOM
111Reserved. Do not use this setting.

Similarly, the output pin configuration for output channel 2 can be done using the OUT2x_CFG[2:0] (P0_R107_D[4:2]) register bits.

The TAD5112 can support a variety of load including headphone, lineout and receiver amplifiers. Load drive configurations are available for each pin independently. OUT1P_DRIVE[1:0] (OUT1x_CFG[7:6]) configures the load drive capability for OUT1P pin. OUT1M_DRIVE[1:0], OUT2P_DRIVE[1:0], OUT2M_DRIVE[1:0] are the output drive control for OUT1M, OUT2P and OUT2M respectively.
