Typical Application Circuits
Their quiescent current is only 0.6µA thereby minimizing
current sensing error.
The ZXCT1084/5/6/7 are fixed
counterparts of the ZXCT1082/3.

The ZXCT1082/1084/1086 have 60V maximum operating
voltage and ZXCT1083/1085/1087 have 40V maximum
operating voltage.
The wide common-mode input voltage range and low
quiescent currents coupled with SOT25 packages make
them suitable for a range of applications; including
automotive and systems operating from industrial 24-28V
rails.

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.
