Triple Wideband, Current-Feedback

OPERATIONAL AMPLIFIER With Disable

DESCRIPTION

FEATURES

The OPA3681 sets a new level of performance for broadband

triple current-feedback op amps. Operating on a very low

6mA/ch supply current, the OPA3681 offers a slew rate and

output power normally associated with a much higher supply

current. A new output stage architecture delivers a high output

current with minimal voltage headroom and crossover distor-

tion. This gives exceptional single-supply operation. Using a

single +5V supply, the OPA3681 can deliver a 1V to 4V output

swing with over 100mA drive current and 150MHz bandwidth.

This combination of features makes the OPA3681 an ideal RGB

line driver or single-supply ADC input driver.

●

WIDEBAND +5V OPERATION: 225MHz (G = +2)

UNITY GAIN STABLE: 280MHz (G = 1)

● HIGH OUTPUT CURRENT: 150mA

● OUTPUT VOLTAGE SWING: ±4.0V

● HIGH SLEW RATE: 2100V/µs

● LOW SUPPLY CURRENT: 6mA/ch

● LOW DISABLED CURRENT: 300µA/ch

● IMPROVED HIGH FREQUENCY PINOUT

The OPA3681’s low 6mA/ch supply current is precisely trimmed

at 25°C. This trim, along with low drift over temperature,

guarantees lower guaranteed maximum supply current than

competing products. System power may be further reduced by

using the optional disable control pin. Leaving this disable pin

open, or holding it high, gives normal operation. If pulled low,

the OPA3681 supply current drops to less than 300µA/ch while

the output goes into a high impedance state. This feature may be

used for power savings or for video MUX applications.
