Transition Control (Address 06h)
ADC3 Single-Ended Mode (ADC3 SINGLE)
Default = 0
0 - Disabled; Differential input to ADC
1 - Enabled; Single-Ended input to ADC
Function:
When disabled, this bit removes the 4:2 multiplexer from the signal path of ADC3 allowing a differential
input. When enabled, this bit allows the user to choose between four single-ended inputs to ADC3, using
the AIN5_MUX and AIN6_MUX bits. See
descriptions.
Analog Input Ch. 5 Multiplexer (AIN5_MUX)
Default = 0
0 - Single-Ended Input AIN5A
1 - Single-Ended Input AIN5B
Function:
ADC3 can accept single-ended input signals when the ADC3 SINGLE bit is enabled. The AIN5_MUX bit
selects between two input channels (AIN5A or AIN5B) to be sent to ADC3 in Single-Ended Mode. This bit
is ignored when the ADC3_SINGLE bit is disabled. See
Analog Input Ch. 6 Multiplexer (AIN6_MUX)
Default = 0
0 - Single-Ended Input AIN6A
1 - Single-Ended Input AIN6B
Function:
ADC3 can accept a single-ended input signal when the ADC3 SINGLE bit is enabled. The AIN6_MUX bit
selects between two input channels (AIN6A or AIN6B) to be sent to ADC3 in Single-Ended Mode. This bit
is ignored when the ADC3_SINGLE bit is disabled. See
Single Volume Control (DAC_SNGVOL, ADC_SNGVOL)
Default = 0
Function:
The individual channel volume levels are independently controlled by their respective Volume Control reg-
isters when this function is disabled. When enabled, the volume on all channels is determined by the
AOUT1 and AIN1 Volume Control register and the other Volume Control registers are ignored.
