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 voltagefrom 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.
