ADC CONTROL & DAC DE-EMPHASIS (ADDRESS 05H)
7.6.1
ADC1-2 HIGH PASS FILTER FREEZE (ADC1-2_HPF FREEZE)
Default = 0
Function:
When this bit is set, the internal high-pass filter will be disabled for ADC1 and ADC2.The current DC
offset value will be frozen and continue to be subtracted from the conversion result. See “ADC Digital
Filter Characteristics” on page 15.
7.6.2
DAC DE-EMPHASIS CONTROL (DAC_DEM)
Default = 0
0 - No De-Emphasis
1 - De-Emphasis Enabled (Auto-Detect Fs)
Function:
Enables the digital filter to maintain the standard 15
μ
s/50
μ
s digital de-emphasis filter response at the
auto-detected sample rate of either 32, 44.1, or 48 kHz. De-emphasis will not be enabled, regardless
of this register setting, at any other sample rate.
7.6.3
ADC1 SINGLE-ENDED MODE (ADC1 SINGLE)
Default = 0
0 - Disabled; Differential input to ADC1
1 - Enabled; Single-Ended input to ADC1
Function:
When enabled, this bit allows the user to apply a single-ended input to the positive terminal of ADC1.
+6 dB digital gain is automatically applied to the serial audio data of ADC1. The negative leg must be
driven to the common mode of the ADC. See Figure 20 on page 49 for a graphical description.
7.6.4
ADC2 SINGLE-ENDED MODE (ADC2 SINGLE)
Default = 0
0 - Disabled; Differential input to ADC2
1 - Enabled; Single-Ended input to ADC2
Function:
When enabled, this bit allows the user to apply a single-ended input to the positive terminal of ADC2.
+6 dB digital gain is automatically applied to the serial audio data of ADC2. The negative leg must be
driven to the common mode of the ADC. See Figure 20 on page 49 for a graphical description.
