1.
Ratiometric (proportional to Vsup).
2.
When the analog output pin (A_Out) is used in differential
mode (i.e. Vout=A_Out-CO_Out).
3. Device saturates for B>Bfs but is not damaged.
4. Specification correction: Was: 290 to 310
V/T, Now: 270 to 290 V/T
5. All parts manufactured to date have been calibrated
to 280 10V/T

Note
The programming data of the sensors are stored in an internal
shift register. Strong electrostatic discharges may change
the programmed parameters. To help protect the sensors
from such disruption please follow the guidelines below
when installing the sensors.
• Place a capacitor between VDD and GND in close
proximity to the sensor.
• Use shielded, twisted pair cables whenever possible.
• Use a good power supply with adequate EMI protection.
• Do not use the power supply to power other equipment
or devices.
• Connect the sensor programming voltage and clock
inputs to VDD. Connect the programming data input to GND.
Sentron products are not to be used in devices or assemblies if the failure in any way of the Sentron
product could cause that device, assembly or associated system to become hazardous or unsafe.
