4. If using the noise shaping requantizer (NSR) feature of the
AD6672 , the settings in the
ADCBase 0
tab must be
changed (see Figure 11). The NSR Enable checkbox must
be selected under the NOISE SHAPED REQUANTIZER
1(3C) section. This enables the circuitry in the AD6672 .
To select the bandwidth mode, use the NSR Mode drop-
down box in the
NOISE SHAPED REQUANTIZER 1(3C)
section. Upon selecting the bandwidth mode, select the
desired tuning word in the
NSR Tuning drop-down menu
under the NOISE SHAPED REQUANTIZER TUNING(3E)
section.
