Product Summary

The OPA2822U is a Dual Wideband low Noise Operational Amplifier. The OPA2822U offers very low 2.0nV/√￣Hz input noise in a wideband, unity-gain stable, voltage-feedback architecture. Intended for xDSL receiver applications, the OPA2822U also supports this low input noise with exceptionally low harmonic distortion, particularly in differential configurations. Adequate output current is provided to drive the potentially heavy load of a passive filter between this amplifier and the codec. Harmonic distortion for a 2VPP differential output operating from +5V to +12V supplies is ≤–100dBc through 1MHz input frequencies. Operating on a low 4.8mA/ch supply current, the OPA2822U can satisfy all xDSL receiver requirements over a wide range of possible supply voltages—from a single +5V condition, to ±5V, up to a single +12V design. The applications of the OPA2822U include xDSL differential line receivers, high dynamic range ADC drivers, low noise PLL integrators, trans-impedance amplifiers, precision baseband I/Q amplifiers, active filters.
