Notes:
4. VSENSE = "VS+" - "VS-"
5. All Min and Max specifications over full temperature range are guaranteed by design and characterization
6. 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 VSENSE = 0V always being positive.
7. For VSENSE > 10mV, the internal voltage-current converter is fully linear. This enables a true offset to be defined and used. VO(10) is expressed
as the variance about an output voltage of 100mV>
8. Temperature dependent measurements are extracted from characterization and simulation results.
