†
All parameters are measured under open-loop conditions with zero common-mode input voltage. For conditions shown as MIN or MAX, use the
appropriate value specified under recommended operating conditions.
NOTES: 5. Total unadjusted error includes offset, full-scale, linearity, and multiplexer errors.
6. The MSB-first data is output directly from the comparator and, therefore, requires additional delay to allow for comparator response
time. LSB-first data applies only to TLC0832.
