Notes:
1. All power supplies must be adequately decoupled.
2. ON Semiconductor recommends a resistor value of 1.5 kW, but a greater value may be used for slower two−wire speed.
3. This pull−up resistor is not required if the controller drives a valid logic level on S
CLK
at all times.
4. ON Semiconductor recommends that VDD_SLVS pad (only available in bare die) is left unconnected.
5. ON Semiconductor recommends that 0.1 mF and 10 mF decoupling capacitors for each power supply are mounted as
close as possible to the pad. Actual values and results may vary depending on layout and design considerations.
Check the AR0130 demo headboard schematics for circuit recommendations.
6. ON Semiconductor recommends that analog power planes are placed in a manner such that coupling with the digital
power planes is minimized.
7. I/O signals voltage must be configured to match V
DD
_IO voltage to minimize any leakage current.
