Figure 37. AD1843 Modem Mode Frequency Response Plots (Full-Scale Line-Level Inputs, 0 dB Gain)

Based on 7.2 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 beneficial

roll-off of the AD1843 analog filters. Out-of-band images will be attenuated by an additional 31.4 dB

at 100 kHz.
