4. Application information
The SCA6X0 should be powered from a well regulated 5 V DC power supply. Coupling of digital
noise to the power supply line should be minimized. 100nF filtering capacitor between VDD pin 8
and GND plane must be used. If regulator is placed far from component for example other PCB it
is recommend adding more capacitance between VDD and GND to ensure current drive capability
of the system. For example 470 pF and 1uF capacitor can be used.
The SCA6X0 has a ratiometric output. To get the best performance use the same reference
voltage for both the SCA6X0 and Analog/Digital converter.
Locate the 100nF power supply filtering capacitor close to VDD pin 8. Use as short a trace length
as possible. Connect the other end of capacitor directly to the ground plane. Connect the GND pin
4 to underlying ground plane. Use as wide ground and power supply planes as possible. Avoid
narrow power supply or GND connection strips on PCB.

Notes:
It is important that the part is parallel to the PCB plane and that there is no angular alignment
error from intended measuring direction during assembly process.
1° mounting alignment error will increase the cross-axis sensitivity by 1.7%
1° mounting alignment error will change the output by 17 mg
Wave soldering is not recommended
Ultrasonic cleaning is not allowed
A supply voltage by-pass capacitor (> 100 nF) is recommended
