open-in-new Find other High-speed op amps (GBW>=50MHz)

Description

The OPA2613 offers very low 1.8nV√Hz input noise in a wideband, unity-gain stable, voltage-feedback architecture. Intended for xDSL driver applications, the OPA2613 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 twisted-pair line. Harmonic distortion for a 2VPP differential output operating from +5V to +12V supplies is ± -95dBc through 1MHz input frequencies. Operating on a low 6.0mA/ch supply current, the OPA2613 can satisfy most xDSL driver requirements over a wide range of possible supply voltage—from a single +5V condition, to ±5V, on up to a single +12V design.

General-purpose applications on a single +5V supply will benefit from the high input and output voltage swing available on this reduced supply voltage. Low-cost precision integrators for PLLs will also benefit from the low voltage noise and offset voltage. Baseband I/Q receiver channels can achieve almost perfect channel match with noise and distortion to support signals through 5MHz with > 14-bit dynamic range.
