Application Hints (Continued)
Each amplifier is individually biased by a zener reference
which allows normal circuit operation on ±6.0V power sup-
plies. Supply voltages less than these may result in lower
gain bandwidth and slew rate.
The amplifiers will drivea2k
load resistance to ±10V over
the full temperature range. If the amplifier is forced to drive
heavier load currents, however, an increase in input offset
voltage may occur on the negative voltage swing and finally
reach an active current limit on both positive and negative
swings.
Precautions should be taken to ensure that the power supply
for the integrated circuit never becomes reversed in polarity
or that the unit is not inadvertently installed backwards in a
socket as an unlimited current surge through the resulting
forward diode within the IC could cause fusing of the internal
conductors and result in a destroyed unit.
As with most amplifiers, care should be taken with lead
dress, component placement and supply decoupling in order
to ensure stability. For example, resistors from the output to
an input should be placed with the body close to the input to
minimize “pick-up” and maximize the frequency of the feed-
back pole by minimizing the capacitance from the input to
ground.
A feedback pole is created when the feedback around any
amplifier is resistive. The parallel resistance and capacitance
from the input of the device (usually the inverting input) to AC
ground set the frequency of the pole. In many instances the
frequency of this pole is much greater than the expected
3 dB frequency of the closed loop gain and consequently
there is negligible effect on stability margin. However, if the
feedback pole is less than approximately 6 times the ex-
pected 3 dB frequency a lead capacitor should be placed
from the output to the input of the op amp. The value of the
added capacitor should be such that the RC time constant of
this capacitor and the resistance it parallels is greater than or
equal to the original feedback pole time constant.
