PRECAUTIONS
Inter-channel Crosstalk
MB88361 2-channel converter, requiring special mounting methods minimize crosstalk between analog output pins. Specifically, recommended that board designs should emphasize prevention large coupling capacities between analog output lines. (See sTYPICAL CHARACTERISTIC CURVES.)
Prevention Switching Noise
reduce superimposed switching noise analog output signal absolute minimum, recommended that noise limiting capacitor between VCCA VCCD pins placed close possible pins connected A.GND D.GND pins.
Power Supply Patterns
Power supply patterns connected A.GND B.GND pins should possible order reduce parasitic impedance.
