DESCRIPTION
The OPA2670 provides the high output current and
low distortion required in emerging xDSL and Power
Line Modem driver applications. Operating on a
single +12V supply, the OPA2670 consumes a low
30.5mA quiescent current to deliver a very high
700mA output current. This output current supports
even the most demanding xDSL requirements with
greater than 450mA minimum output current (+25°C
minimum value) with low harmonic distortion. Differential driver applications deliver less than
–71dBc distortion at the peak upstream power levels
of full-rate ADSL. The high 420MHz bandwidth also
supports the most demanding VDSL2 line driver
requirements.
Power control features are included to allow system
power to be minimized. Two logic control lines allow
four quiescent power settings, including full power,
66% power, 33% power, and shutdown.
