OP249
–10–
REV. E
The OP249 was carefully designed to provide symmetrically
matched slew characteristics in both the negative and positive
directions, even when driving a large output load.
An amplifier’s slewing limitation determines the maximum
frequency at which a sinusoidal output can be obtained without
significant distortion. It is, however, important to note that the
nonsymmetric stewing typical of previously available JFET
amplifiers adds a higher series of harmonic energy content to
the resulting response—and an additional dc output component.
Examples of potential problems of nonsymmetric slewing
behavior could be in audio amplifier applications, where a natural
low distortion sound quality is desired, and in servo or signal
processing systems where a net dc offset cannot be tolerated.
The linear and symmetric stewing feature of the OP249 makes
it an ideal choice for applications that will exceed the full-power
bandwidth range of the amplifier.

As with most JFET-input amplifiers, the output of the OP249
may undergo phase inversion if either input exceeds the speci-
fied input voltage range. Phase inversion will not damage the
amplifier, nor will it cause an internal latch-up condition.
Supply decoupling should be used to overcome inductance and
resistance associated with supply lines to the amplifier. A 0.1
F
and a 10
F capacitor should be placed between each supply
pin and ground.
OPEN-LOOP GAIN LINEARITY
The OP249 has both an extremely high open-loop gain of
1 kV/mV minimum and constant gain linearity. This feature of
the OP249 enhances its dc precision, and provides superb accu-
racy in high closed-loop gain applications. Figure 8 illustrates
the typical open-loop gain linearity—high gain accuracy is assured,
even when driving a 600
load.
OFFSET VOLTAGE ADJUSTMENT
The inherent low offset voltage of the OP249 will make offset
adjustments unnecessary in most applications. However, where
a lower offset error is required, balancing can be performed with
simple external circuitry, as illustrated in Figures 9 and 10.

Figure 10. Offset Adjust for Noninverting Amplifier
Configuration
In Figure 9, the offset adjustment is made by supplying a small
voltage at the noninverting input of the amplifier. Resistors R1
and R2 attenuates the pot voltage, providing a
±2.5 mV (with
VS =
±15 V) adjustment range, referred to the input. Figure 10
illustrates offset adjust for the noninverting amplifier configura-
tion, also providing a
±2.5 mV adjustment range. As indicated
in the equations in Figure 10, if R4 is not much greater than R2,
there will be a resulting closed-loop gain error that must be
accounted for.
