PRECAUTIONS
The MB88361 is a 2-channel D/A converter, requiring the use of special mounting methods to minimize crosstalk
between analog output pins.
Specifically, it is recommended that PC board designs should emphasize the prevention of large coupling
capacities between analog output lines. (See TYPICAL CHARACTERISTIC CURVES.)
To reduce superimposed switching noise on the analog output signal to an absolute minimum, it is recommended
that a noise limiting capacitor between the V
connected to the A.GND and D.GND pins.
Power supply patterns connected to the A.GND and B.GND pins should be as possible in order to reduce
parasitic impedance.
CCA

pins be placed as close as possible to the pins and
