Application Information
Operation at Various Supply Voltages
The HA-5221/5222 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 20k
trim pot will allow an offset voltage adjustment of
about 10mV.
Capacitive Loading Considerations
When driving capacitive loads >80pF, a small resistor, 50
to 100
, should be connected in series with the output and
inside the feedback loop.
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 over-
driven into the positive rail is 10.6
μ
s. When driven into the
negative rail the maximum recovery time is 3.8
μ
s.
Input Protection
The HA-5221/5222 has built in back-to-back protection
diodes which limit the maximum allowable differential input
voltage to approximately 5V. If the HA-5221/5222 will be
used in circuits where the maximum differential voltage may
be exceeded, then current limiting resistors must be used.
The input current should be limited to a maximum of 10mA.
PC Board Layout Guidelines
When designing with the HA-5221 or the HA-5222, good
high frequency (RF) techniques should be used when build-
ing a PC board. Use of ground plane is recommended.
Power supply decoupling is very important. A 0.01
μ
F to
0.1
μ
F high quality ceramic capacitor at each power supply
pin with a 2.2
μ
F to 10
μ
F tantalum close by will provide excel-
lent 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 induc-
tance.
