The input to the ADC is differential in order to provide common-mode noise rejection and increase the input
dynamic range. Figure 2–3 shows the analog input signals used in a differential configuration to achieve a
6.4 V
I(PP)
differential swing with a 3.2 V
I(PP)
swing per input line.

2.3
The modulator is a fourth-order sigma-delta modulator with 64 times oversampling. The ADC provides
high-resolution, low-noise performance from a 1-bit converter using oversampling techniques.
Sigma-Delta Modulator for the ADC
2.4
The decimation filter after the sigma-delta ADC modulator reduces the digital data rate to the sampling rate
of LRCKA. This is accomplished by decimating with a ratio of 1:64.

2.5
The high-pass filter removes dc from the input of the ADC. The output of this filter is a 2’s-complement data
word of 20 bits serially clocked out. If the input value exceeds the full range of the converter, the output of
the high-pass filter is held at the appropriate extreme until the input returns to the analog input range of the
TLC320AD75C.
