Notes:
1. For the ZXCT1082/83 VSENSE = “VSUPPLY” – “VLOAD“ where VLOAD is the load voltage or the lower potential side of the sense resistor.
For the ZXCT1083/84/85/86 VSENSE = “VS+” – “VS-“
2. VIO is extrapolated from measurements for the gain-error test.
3. For VSENSE > 10mV, the internal voltage-current converter is fully linear. This enables a true offset to be defined and used.
4. Gain or transconductance error is calculated by applying two values of VSENSE and calculating the error of the slope vs. the ideal.
