DESCRIPTION

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.

General-purpose applications on a single +5V supply will

benefit from the high input and output voltage swing

available on this reduced supply 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.
