C0028-E-00 1999/9
Reference current circuit
To determine input reference current, connect 12k
±
1% resistor.
Power Supply
To attenuate the power supply noise, connect capacitors between VDD and VSS respectively.
The value of the capacitance AK2548 need depend on the condition of the power supply line.
Please decide the value of the capacitance after your evaluation.
