APPLICATIONS
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 F to 0.1 F). For high drive current applications use
low ESR bypass capacitors (1 F to 10 F 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

used, a parallel capacitor of value

dynamic performance. For unity-gain applications where
