OPA2614IDTJRG3

双路，高增益带宽，高输出电流运算与限流放大器 Dual, High Gain Bandwidth, High Output Current Operational Amplifier with Current Limit

DESCRIPON

The OPA2614 offers very low 1.8nV√Hz input noise in a wideband, high gain bandwidth, voltage-feedback architecture. Intended for xDSL driver applications, the OPA2614 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 ≤ −80dBc through 1MHz input frequencies. Operating on a low 6.0mA/ch supply current, the OPA2614 can satisfy most xDSL driver requirements over a wide range of possible supply voltagefrom a single +5 condition, to ±5V, on up to a single +12V design.
