Notes: 4. Applies only in track mode. When converting or calibrating, input capacitance will not exceed 15 pF.
5. Measured from falling transition on HOLD to falling transition on EOC.
6. Conversion, acquisition, and throughput times depend on CLKIN, sampling, and calibration conditions.
The numbers shown assume sampling and conversion is synchronized with the CS5012A/14/16 ’s
conversion clock, interleave calibrate is disabled, and operation is from the full-rated, external clock.
Refer to the section Conversion Time/Throughput for a detailed discussion of conversion timing.
7. All outputs unloaded. All inputs CMOS levels.
8. With 300 mV p-p, 1 kHz ripple applied to each analog supply separately in bipolar mode. Rejection
improves by 6 dB in the unipolar mode to 90 dB. Figure 13 shows a plot of typical power supply
rejection versus frequency.
