Input Protection
The HA-5101 has built-in back-to-back protection diodes
which will limit the differential input voltage to approximately
7V. If the HA-5101 will be used in conditions where that volt-
age may be exceeded, then current limiting resistors must
be used. No more than 25mA should be allowed to flow in
the HA-5101’s input.
Output Saturation
When an op amp is overdriven, output devices can saturate
and sometimes take a long time to recover. Saturation can
be avoided (sometimes) by using circuits such as:
If saturation cannot be avoided the HA-5101 recovers from a
25% overdrive in about 6.5µs (see photo).
