PRODUCTION DATA.
Refer to the PDF data sheet for device specific package drawings
The bandwidth of the digital filter depends on the data rate, filter type and order. Be aware that the bandwidth of the entire system is the combined response of the digital filter, the antialias filter and the use of external analog filters. Table 4 lists the bandwidth of the digital filter versus data rate and filter mode.
