17. Conversion time scales directly to the master clock speed. The times shown are for synchronous, internal loopback
18. The CS5102A requires 6 clock cycles of coarse charge, followed by a minimum of 5.625 µs of fine charge. FRN
19. Throughput is the sum of the acquisition and conversion times. It will vary in accordance with conditions affecting
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

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