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 (0.4μs) 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.
