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. Rev.
