Figure 15 illustrates the device with a small signal 1/1,000,000 of full scale. The signal input for figure 14

is about 8.2 microvolts peak to peak, or about 17 codes peak to peak. Figure 16 illustrates the converter

with a signal at about 2.6 microvolts peak to peak, or about 5 codes peak to peak. The CS5560 achieves

superb performance with this small signal. And the noise floor exhibits no spurious components due to

digital interference from the on chip logic.
