AD1852

Rev. A | Page 9 of 20

TYPICAL PERFORMANCE CHARACTERISTICS

Figure 8 to Figure 13 show the calculated frequency response of the digital interpolation filters. Figure 14 to Figure 25 show the performance of

the AD1852 as measured by an Audio Precision System 2 Cascade. For the wideband plots, the noise floor shown in the plots is higher

than the actual noise floor of the AD1852. This is caused by the higher noise floor of the high bandwidth ADC used in the Audio Precision

measurement system. The two-tone test shown in Figure 16 is per the SMPTE standard for measuring intermodulation distortion.
