APPLICATIONS INFORMATION
WUU
U
The LT1220 may be inserted directly into HA2505/15/25,
HA2541/2/4, AD817, AD847, EL2020, EL2044 and LM6361
applications, provided that the nulling circuitry is removed.
The suggested nulling circuit for the LT1220 is shown in
the following figure.
Layout and Passive Components
The LT1220 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 (0.01µF to 0.1µF).
For high driver current applications use low ESR bypass
capacitors (1µF to 10µF 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.
