Description
Ground Reference for Digital Circuitry.
Logic Power Supply Input. The voltage supplied at this pin determines at what voltage the interface logic of
the device operates.
Data Output Bit for Overranging. If the overrange feature is not used, this pin should be pulled to DGND via a
100 kΩ resistor.
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.
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 are also cleared on this edge. Holding this pin low
keeps the part in a reset state.
Operating Mode Logic Input. See Table 8 for details.
Operating Mode Logic Input. See Table 8 for details.
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 is clipped to all 1s or all 0s, respectively. Further details
are given in the Offset/Overrange section.
