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.
Typical Application Circuits
Their quiescent current is only 0.6µA thereby minimizing current
sensing error.

Voltage output
Output pin.
Ground pin.
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, RGT, 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.
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.
This is the analogue supply and provides power to internal circuitry.

Stresses greater than the 'Absolute Maximum Ratings' specified above, may cause permanent damage to the device. These are stress ratings only;
functional operation of the device at these or any other conditions exceeding those indicated in this specification is not implied. Device reliability may be
affected by exposure to absolute maximum rating conditions for extended periods of time.
Semiconductor devices are ESD sensitive and may be damaged by exposure to ESD events. Suitable ESD precautions should be taken when handling
and transporting these devices.
Notes:
5. 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-“

5. 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-“
7. VIO is extrapolated from measurements for the gain-error test.
8. For VSENSE > 10mV, the internal voltage-current converter is fully linear. This enables a true offset to be defined and used.
9. Gain or transconductance error is calculated by applying two values of VSENSE and calculating the error of the slope vs. the ideal.
