POWER SUPPLY BYPASSING

Bypassing the power supply is necessary to maintain low power supply impedance across frequency. Both

positive and negative power supplies should be bypassed individually by placing 0.01

μF ceramic capacitors

directly to power supply pins and 2.2

μF tantalum capacitors close to the power supply pins.

TERMINATION

In high frequency applications, reflections occur if signals are not properly terminated. Figure 48 shows a

properly terminated signal while Figure 49 shows an improperly terminated signal.
