1
Dynamic performance is achieved with a burst SCLK. Operating a free running SCLK during acquisition phase degrades dynamic performance.

4
Sample tested during initial release to ensure compliance.
5
SCLK is operating in burst mode and
CS
is idling high. With a free running SCLK and
CS
pulled low, the I
DD
static current is increased by 30 µA typical at V
DD
= 5.25 V.
6
SCLK is operating in burst mode and
CS
is idling high. With a free running SCLK and
CS
pulled low, the I
DRIVE
static current is increased by 32 µA typical at V
