PRODUCTION DATA.
Filter type C, along with an AOSR of 32, is specially designed for 192-kSPS operation of the ADC. The pass band, which extends up to 0.11 × fS (corresponds to 21 kHz), is suited for audio applications. Table 12 specifies the performance of filter C. Figure 42 shows the frequency response for filter C.
