OP162/OP262/OP462
UNUSED AMPLIFIERS
It is recommended that any unused amplifiers in a dual or a
quad package be configured as a unity-gain follower with a
1 kΩ feedback resistor connected from the inverting input to
the output, and the noninverting input tied to the ground plane.
POWER-ON SETTLING TIME
The time it takes for the output of an op amp to settle after a
supply voltage is delivered can be an important consideration in
some power-up-sensitive applications. An example of this
would be in an A/D converter where the time until valid data
can be produced after power-up is important.
The OPx62 family has a rapid settling time after power-up.
Figure 38 shows the OP462 output settling times for a single-
supply voltage of V
used to find the power-on settling times for the device.

CAPACITIVE LOAD DRIVE
The OP162/OP262/OP462 are high speed, extremely accurate
devices that tolerate some capacitive loading at their outputs. As
load capacitance increases, unity-gain bandwidth of an OPx62
device decreases. This also causes an increase in overshoot and
settling time for the output. Figure 41 shows an example of this
with the device configured for unity gain and driving a 10 kΩ
resistor and 300 pF capacitor placed in parallel.
By connecting a series R-C network, commonly called a
“snubber” network, from the output of the device to ground,
this ringing can be eliminated and overshoot can be
significantly reduced. Figure 40 shows how to set up the
snubber network, and Figure 42 shows the improvement in
output response with the network added.
