If power to this integrated circuit is applied in reverse

polarity, or if the IC is installed backwards in a socket, large

unlimited current surges will occur through the device that

may result in device destruction.

As usual with most high frequency amplifiers, proper lead

dress, component placement and PC board layout should be

exercised for optimum frequency performance. For

example, long unshielded input or output leads may result in

unwanted input/output coupling. In order to preserve the

relatively low input capacitance associated with these

amplifiers, resistors connected to the inputs should be

immediately adjacent to the input pin to minimize additional

stray input capacitance. This not only minimizes the input

pole for optimum frequency response, but also minimizes

extraneous “pick up” at this node. Supply decoupling with

adequate capacitance immediately adjacent to the supply pin

is also important, particularly over temperature, since many

types of decoupling capacitors exhibit great impedance

changes over temperature.

The output of any one amplifier is current limited and thus

protected from a direct short to ground. However, under

such conditions, it is important not to allow the device to

exceed the maximum junction temperature rating. Typically

for ±15 V supplies, any one output can be shorted

continuously to ground without exceeding the maximum

temperature rating.
