Saturation Recovery
When an op amp is over driven, output devices can saturate
and sometimes take a long time to recover. By clamping the
input, output saturation can be avoided. If output saturation
can not be avoided, the maximum recovery time when
overdriven into the positive rail is 10.6
μ
s. When driven into
the negative rail the maximum recovery time is 3.8
μ
s.
Input Protection
The HA-5221 has built in back-to-back protection diodes
which limit the maximum allowable differential input voltage
to approximately 5V. If the HA-5221 is used in circuits where
the maximum differential voltage may be exceeded, then
current limiting resistors must be used. The input current
should be limited to a maximum of 10mA.
PC Board Layout Guidelines
When designing with the HA-5221, good high frequency
(RF) techniques should be used when building a PC board.
Use of ground plane is recommended. Power supply
decoupling is very important. A 0.01

F tantalum close by will provide excellent decoupling.
Chip capacitors produce the best results due to ease of
placement next to the op amp and basically no lead
inductance. If leaded capacitors are used, the leads should
be kept as short as possible to minimize lead inductance.
