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 2V_PP 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.
