The LT1221 is stable in noise gains of 4 or greater and may
be inserted directly into HA2520/2/5, HA2541/2/4, AD817,
AD847, EL2020, EL2044 and LM6361 applications, pro-
vided that the nulling circuitry is removed and the ampli-
fier configuration has a high enough noise gain. The
suggested nulling circuit for the LT1221 is shown in the
following figure.

Layout and Passive Components
The LT1221 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
μ
F to 0.1
μ
F).
For high drive current applications use low ESR bypass
capacitors (1
μ
F to 10
μ
F tantalum). Sockets should be
avoided when maximum frequency performance is re-
quired, although low profile sockets can provide reason-
able performance up to 50MHz. For more details see
Design Note 50. Feedback resistors greater than 5k are not
recommended because a pole is formed with the input
capacitance which can cause peaking or oscillations.
Input Considerations
Bias current cancellation circuitry is employed on the
inputs of the LT1221 so the input bias current and input
