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:

V+

R1

R2

+

-

R3

VSOURCE

R4

V-

If saturation cannot be avoided the HA-5101 recovers from a

25% overdrive in about 6.5µs (see photo).

NOTE: Proper decoupling is always recommended, 0.1µF high quality

capacitor should be at or very near the device’s supply pins.
