APPLICATIO S I FOR ATIO

The LT1194 is a video difference amplifier with a fixed gain

of 10 (20dB). The amplifier has two uncommitted high

input impedance (+) and (–) inputs that can be used either

differentially or single-ended. The LT1194 includes a

limiting feature that allows the amplifier to reduce its

limiting feature uses input differential-pair limiting to

prevent overload in subsequent stages. This technique

allows extremely fast limiting action.

Power Supply Bypassing

The LT1194 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.
