OPA2674

SBOS270 − AUGUST 2003

Dual Wideband, High Output Current

Operational Amplifier with Current Limit

F_DEATURES

DESCRIPTION

WIDEBAND +12V OPERATION: 220MHz (G = +4)

UNITY-GAIN STABLE: 250MHz (G = +1)

HIGH OUTPUT CURRENT: 500mA

The OPA2674 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 OPA2674 consumes a low 9mA/ch quiescent

current to deliver a very high 500mA output current. This

output current supports even the most demanding ADSL

CPE requirements with > 380mA minimum output current

(+25°C minimum value) with low harmonic distortion.

Differential driver applications deliver < −85dBc distortion

at the peak upstream power levels of full rate ADSL. The

high 200MHz bandwidth also supports the most

demanding VDSL line driver requirements.

OUTPUT VOLTAGE SWING: 10V

HIGH SLEW RATE: 2000V/µs

LOW SUPPLY CURRENT: 18mA

FLEXIBLE POWER CONTROL: SO-14 Only

OUTPUT CURRENT LIMIT ( 800mA)

A_DPPLICATIONS

POWER LINE MODEM

Power control features are included in the SO-14 package

version to allow system power to be minimized. Two logic

control lines allow four quiescent power settings. These

include full power, power cutback for short loops, idle state

for no signal transmission but line match maintenance,

and shutdown for power off with a high impedance output.

xDSL LINE DRIVERS

CABLE MODEM DRIVERS

MATCHED I/Q CHANNEL AMPLIFIERS

BROADBAND VIDEO LINE DRIVERS

ARB LINE DRIVERS

Specified on 6V supplies (to support +12V operation), the

OPA2674 will also support a single +5V or dual 5V

supply. Video applications will benefit from a very high

output current to drive up to 10 parallel video loads (15Ω)

with < 0.1%/0.1° dG/dP nonlinearity.
