Current output. Voltage output 2 GND Ground pin. 3 S+ This is the positive input of the current monitor. It has a wide common-mode input range. The current through this pin varies with differential sense voltage. An external resistor, R GT, should be connected from S+ to the input side (VSUPPLY) of the sense resistor Should be directly connected to the input side (VSUPPLY) of the sense resistor. 4 S- This is the negative input of the current monitor. It has a wide common-mode input range. An external resistor, RGT, should be connected from S- to the load side (VLOAD) of the sense resistor. Should be directly connected to the load side (VLOAD) of the sense resistor. 5 VCC This is the analogue supply and provides power to internal circuitry.

For the ZXCT1082/83 V SENSE = “VSUPPLY” – “VLOAD“ where VLOAD is the load voltage or the lower potential side of the sense resistor. For the ZXCT1083/84/85/86 V SENSE = “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.
