Power Supply Rejection:
20. The CS5102A requires 6 clock cycles of coarse charge, followed by a minimum of 5.625
21. Throughput is the sum of the acquisition and conversion times. It will vary in accordance with conditions
22. All outputs unloaded. All inputs at VD+ or DGND. See table below for power dissipation vs. clock frequency.
23. With 300 mV p-p, 1 kHz ripple applied to each supply separately in the bipolar mode. Rejection
internal loopback (FRN mode). In PDT, RBT, and SSC modes, asynchronous delay between the falling
edge of HOLD and the start of conversion may add to the apparent conversion time. This delay will
not exceed 1 master clock cycle + 140 ns.
FRN mode allows 9 clock cycles for fine charge which provides for the minimum 5.625
clock, however; in PDT, RBT, or SSC modes, at clock frequencies less than 1.6 MHz, fine charge may
be less than 9 clock cycles.
affecting acquisition and conversion times, as described above.
improves by 6 dB in the unipolar mode to 90 dB. Figure 23 shows a plot of typical power supply
rejection versus frequency.
