CAL_STRT_N
pulse that initiates the ADC calibration sequence. The
pulse must not be actuated for 1 microsecond after
either power-up or removal of the sensor from a
power-down state. Users may find it easiest to cali-
brate by means of the logic reset.
CAL_DONE_N
output pulse that is asserted when the ADC calibration
is complete. The device will automatically initiate a

this sequence, in cases where it is initiated by a reset, is
still with the CAL_DONE_N signal. This process is
complete within 112 SYSCLK cycles of CAL_STRT_N.

LRST_N
that resets the digital logic. It puts all logic into a
known state (all flip-flops are reset). This signal also
initiates an ADC calibration sequence.
LRST_N is a two-clock cycle-wide active-low pulse
