HA-5221

Data Sheet April 2000

100MHz, Low Noise, Precision
Operational Amplifier

The HA-5221 is a single high performance dielectrically
isolated, op amp, featuring precision DC characteristics while
providing excellent A C char acteristics. Designed for audio,
video,and other demanding applications, noise (3.4nV/√
1kHz), total harmonic distortion (<0.005%), and DC errors are
kept to a minimum.

The precision performance is shown by low offset voltage
(0.3mV), low bias currents (40nA), low offset currents
(15nA), and high open loop gain (128dB). The combination
of these excellent DC characteristics with the fast settling
time (0.4µs) makes the HA-5221 ideally suited for precision
signal conditioning.

The unique design of the HA-5221 gives it outstanding AC
characteristics not normally associated with precision op
amps, high unity gain bandwidth (35MHz) and high slew rate
(25V/µs). Other key specifications include high CMRR (95dB)
and high PSRR (100dB). The combination of these
specifications will allow the HA-5221 to be used in RF signal
conditioning as well as video amplifiers.

For MIL-STD-883C compliant product and Ceramic LCC
packaging, consult the HA-5221/883C data sheet. (Intersil

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.
