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.

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.
