Preventing Switching Noise To prevent switching noise in the analog output signal, connect noise limiting capacitors to the VCCA and VCCD pins as close to the A.GND and D.GND pins as possible. 2. Power Pattern To reduce parasitic impedance, the PC board pattem to the VCCA, VCCD, A.GND and D.GND pins should be as wide as possible. 9 MB40760 TYPICAL CHARACTERISTICS CURVES 1.Power Supply Current v.s.
