HA-5221

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 AC characteristics. Designed for audio,

video, and other demanding applications, noise (3.4nV/

√Hz at

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 (0.4

µs) 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.
