WIDEBAND +12V OPERATION:

The OPA2670 provides the high output current and

420MHz (G = +5V/V)

low distortion required in emerging xDSL and Power

Line Modem driver applications. Operating on a

•

HIGH OUTPUT CURRENT: 700mA

single +12V supply, the OPA2670 consumes a low

•

30.5mA quiescent current to deliver a very high
