Figure 36. AD1843 Audio Mode Frequency Response Plots (Full-Scale Line-Level Inputs, 0 dB Gain)
Based on 48 kHz sample rate; other sample rates will show slightly different behavior. See the
”Specifications” section for performance limits. The DAC plots do not reflect the additional benefi-
cial roll-off of the AD1843 analog filters. Out-of-band images will be attenuated by an additional
31.4 dB at 100 kHz.
