Application Information
Operation at Various Supply Voltages
The HA-5221 operates over a wide range of supply voltages
with little variation in performance. The supplies may be
varied from
±5V
to
±15V.
See typical performance curves for
variations in supply current, slew rate and output voltage
swing.

Offset Adjustment
The following diagram shows the offset voltage adjustment
configuration for the HA-5221. By moving the potentiometer
wiper towards pin 8 (+BAL), the op amps output voltage will
increase; towards pin 1 (-BAL) decreases the output voltage.
A 20kΩ trim pot will allow an offset voltage adjustment of
about 10mV.
-15V
Capacitive Loading Considerations
When driving capacitive loads >80pF, a small resistor, 50Ω
to 100Ω, should be connected in series with the output and
inside the feedback loop.

HA-5221
Saturation Recovery
When an op amp is over driven, output devices can saturate
and sometimes take a long time to recover. By clamping the
input, output saturation can be avoided. If output saturation
can not be avoided, the maximum recovery time when
overdriven into the positive rail is 10.6µs. When driven into
the negative rail the maximum recovery time is 3.8µs.

PC Board Layout Guidelines
When designing with the HA-5221, good high frequency
(RF) techniques should be used when building a PC board.
Use of ground plane is recommended. Power supply
decoupling is very important. A 0.01µF to 0.1µF high quality
ceramic capacitor at each power supply pin with a 2.2µF to
10µF tantalum close by will provide excellent decoupling.
Chip capacitors produce the best results due to ease of
placement next to the op amp and basically no lead
inductance. If leaded capacitors are used, the leads should
be kept as short as possible to minimize lead inductance.
Input Protection
The HA-5221 has built in back-to-back protection diodes
which limit the maximum allowable differential input voltage
to approximately 5V. If the HA-5221 is used in circuits where
the maximum differential voltage may be exceeded, then
current limiting resistors must be used. The input current
