POWER SUPPLIESDECOUPLING AND LAYOUTCONSIDERATIONS
Powersuppliesto digitalsystemsmaycontainhigh
amplitudespikesand othernoise.Tooptimizeper-
formances of the TS7514 operatingin close prox-
imity to digital systems, supply and ground noise
shouldbe minimized.
Thisinvolvesattentionto powersupply designand
circuit board layout.
The power supplies should be bypassedwith tan-
talumor electrolyticcapacitorsto obtainnoise free
operation. These capacitors should be located
close to the TS7514. The electrolytic type capaci-
tors for improved high frequencyperformance.
Power supplies connections should be short and
direct. Ground loops should be avoided.
