For proper operation Vout should be constrained to the range Vss≤Vout≤Vdd.
Exceeding the absolute maximum ratings may cause permanent damage. Exposure to absolute-maximumrated conditions for extended periods may affect device reliability.

The column Test indicates if the specific parameter is tested in production. Following symbols are used:
V: the specific parameter is tested in production
X: the specific parameter is verified in characterisation, but is not tested in production (e.g. timings and capacitances)
D: the specific parameter is guaranteed by design and is not tested as such in production

7 Applications Information
A typical connection diagram is shown in the figure below. A load resistor RL is needed to get the voltage
level out. The load capacitance CL is typically formed by the input capacitance of the component that is connected to the sensor output, the wiring capacitance and the output capacitance of the sensor itself.
Decoupling capacitors between Vdd and Vss (1uF in parallel with 100nF) are highly recommended in all configurations.
Recommendation: every change in the application should be agreed by both parties.

Our products are classified and qualified regarding soldering technology, solderability and moisture sensitivity
level according to following test methods:
Reflow Soldering SMD’s (Surface Mount Devices)
•
•
IPC/JEDEC J-STD-020
Moisture/Reflow Sensitivity Classification for Nonhermetic Solid State Surface Mount Devices
(classification reflow profiles according to table 5-2)
EIA/JEDEC JESD22-A113
Preconditioning of Nonhermetic Surface Mount Devices Prior to Reliability Testing
(reflow profiles according to table 2)
