plies to the appropriate ground with a 10μF tantalum
capacitor, to filter power supply noise, in parallel with a
0.1μF capacitor. A combination of 0.01μF in parallel
with high quality 47pF ceramic chip capacitor located
very close to the MAX105 device filters high frequency
noise. A properly designed PC board (see MAX105EV
Kit data sheet) allows the user to connect all analog
supplies and all digital supplies together thereby
requiring only two separate power sources. Decoupling

Thermal Management
The MAX105 is designed for a thermally enhanced 80-
pin TQFP package, providing greater design flexibility,
increased thermal efficiency and a low thermal junc-
tion-case (
