1 Dynamic performance is achieved with a burst SCLK. Operating a free running SCLK during acquisition phase degrades dynamic performance.
2 See the Terminology section.
3 Sample tested during initial release to ensure compliance.
4 SCLK is operating in burst mode and CS is idling high. With a free running SCLK and CS pulled low, the IDD static current is increased by 30 µA typical at VDD = 5.25 V.
5 SCLK is operating in burst mode and CS is idling high. With a free running SCLK and CS pulled low, the IDRIVE static current is increased by 32 µA typical at VDRIVE = 5.25 V.
