3 Description

The OPA2675 provides the high output current

and low distortion required for power-line modem

driver and test and measurement applications. The

OPA2675 operates on power-supplies ranging from

4.5 V to 13 V and consumes a low 16.5 mA/channel

quiescent current to deliver a very high 1000 mA

output current. The OPA2675 can support the most

demanding power-line modem requirements with 850

mA assured minimum output current drive (at 25 °C).

Power control features are included to minimize

system power consumption. Two logic control lines

allow for four quiescent power settings: full power,

75 bias power, 50 bias power and offline mode

with active offline control to present a high impedance

with large signals present at the output pin. The two

channels of OPA2675 can be used independently

as individual op amps or can be configured as a

differential-input to differential-output, high current line

driver.
