APPLICATIONS
The LT1351 may be inserted directly into many high
speed amplifier applications improving both DC and AC
performance, provided that the nulling circuitry is re-
moved. The suggested nulling circuit for the LT1351 is
shown in Figure 1.

Layout and Passive Components
The LT1351 amplifier is easy to apply and tolerant of less
than ideal layouts. For maximum performance (for ex-
ample fast settling time) 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). For details see Design
Note 50.
The parallel combination of the feedback resistor and gain
setting resistor on the inverting input can combine with
the input capacitance to form a pole which can cause
peaking or even oscillations. For feedback resistors greater
than 10k, a parallel capacitor of value, C
should be used to cancel the input pole and optimize
dynamic performance. For applications where the DC
