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. The serial interface output pads can be left unconnected if the parallel output interface is used.
4. 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 the layout and design considerations. Refer to the AR0237AT demo
headboard schematics for circuit recommendations.
5. ON Semiconductor recommends that analog power planes are placed in a manner such that coupling with the digital power planes is
minimized.
6. I/O signals voltage must be configured to match V
DD
_IO voltage to minimize any leakage currents.
7. The EXTCLK input is limited to 6−48 MHz.
