Description
40
D14
Data Output Bit for Overranging. If the overrange feature is not used, this pin should be pulled to DGND via
a 100 k resistor.
41
CONVST
Convert Start Logic Input. A conversion is initiated on the falling edge of the CONVST signal. The input track-
and-hold amplifier goes from track mode to hold mode, and the conversion process commences.
42
RESET
Reset Logic Input. An active low reset pulse must be applied to this pin after power-up to ensure correct
operation. A falling edge on this pin resets the internal state machine and terminates a conversion that may
be in progress. The contents of the offset register will also be cleared on this edge. Holding this pin low
keeps the part in a reset state.
43
MODE2
Operating Mode Logic Input. See Table 8 for details.
44
MODE1
Operating Mode Logic Input. See Table 8 for details.
45
CLIP
Logic Input. A logic high on this pin enables output clipping. In this mode, any input voltage that is greater
than positive full scale or less than negative full scale will be clipped to all 1s or all 0s, respectively. Further
details are given in the Offset/Overrange section.
