APPLICATIO S I FOR ATIO
Power Supply Bypassing
The LT1192 is quite tolerant of power supply bypassing.
In some applications a 0.1µF 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,
RL = 1k.
In most applications, and those requiring good settling
time, it is important to use multiple bypass capacitors. A
0.1µF 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
