(FRN) mode. In PDT, RBT, and SSC modes, asynchronous delay between the falling edge of

of conversion may add to the apparent conversion time. This delay will not exceed 1 master clock cycle + 140 ns.

18. The CS5102A requires 6 clock cycles of coarse charge, followed by a minimum of 5.625

µs of fine charge. FRN

mode allows 9 cycles for fine charge which provides for the minimum 5.625

µs with a 1.6 MHz clock, however; in

PDT, RBT, or SSC modes and at clock frequencies of less than 1.6 MHz, fine charge may be less than 9 clock

cycles.

19. Throughput is the sum of the acquisition and conversion times. It will vary in accordance with conditions affecting

acquisition and conversion times, as described above.

20. All outputs unloaded. All inputs at VD+ or DGND. See table below for power dissipation versus clock frequency.

21. With 300 mV p-p, 1-kHz ripple applied to each supply separately in the bipolar mode. Rejection improves by 6 dB

in the unipolar mode to 90 dB. Figure 25 shows a plot of typical power supply rejection versus frequency.
