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 2V_PP 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 +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. 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.
Very high line power requirements can be supported using
the thermally-enhanced heat slug package. Soldered into
a standard printed circuit board, this heat slug reduces the
thermal impedance junction-to-ambient to < 50°C/W.
