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 (0.4µs) 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.
