Layout and Passive Components

The LT1355/LT1356 amplifiers are easy to use and toler-

ant of less than ideal layouts. For maximum performance

(for example, fast 0.01% settling) use a ground plane,

short lead lengths, and RF-quality bypass capacitors

(0.01

µF to 0.1µF). For high drive current applications use

low ESR bypass capacitors (1

µF to 10µF tantalum).

The parallel combination of the feedback resistor and gain

setting resistor on the inverting input combine with the

input capacitance to form a pole which can cause peaking

or oscillations. If feedback resistors greater than 5k

Ω are

used, a parallel capacitor of value

should be used to cancel the input pole and optimize

dynamic performance. For unity-gain applications where
