Notes: 19. Conversion time scales directly to the master clock speed. The times shown are for synchronous,

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.

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

µs of fine charge.

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

µs with an 1.6 MHz

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.

21. 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.

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

improves by 6 dB in the unipolar mode to 90 dB. Figure 23 shows a plot of typical power supply

rejection versus frequency.
