NOTES:
(a) V
SENSE
= "V
SENSE+
" - "V
SENSE-
"
(b) The ZXCT1080 operates from a positive power rail and the internal voltage-current converter current flow is
unidirectional; these result in the output offset voltage for V
SENSE
= 0V always being positive.
(c) For V
SENSE
> 10mV, the internal voltage-current converter is fully linear. This enables a true offset to be defined and
used. V
O(10)
is expressed as the variance about an output voltage of 100mV>
(d) Temperature dependent measurements are extracted from characterization and simulation results.
(e) All Min and Max specifications over full temperature range are guaranteed by design and characterisation
