APPLICATIO S I FOR ATIO

Power Supply Bypassing

The LT1192 is quite tolerant of power supply bypassing.

In some applications a 0.1

µF ceramic disc capacitor

placed 1/2 inch from the amplifier is all that is required. A

scope photo of the amplifier output with no supply by-

passing is used to demonstrate this bypassing tolerance,

In most applications, and those requiring good settling

time, it is important to use multiple bypass capacitors. A

0.1

µF ceramic disc in parallel with a 4.7µF tantalum is

recommended. Two oscilloscope photos with different

bypass conditions are used to illustrate the settling time

characteristics of the amplifier. Note that although the

output waveform looks acceptable at 1V/DIV, when
