FEATURES

DESCRIPTION

The OPA3680 represents a major step forward in

unity gain stable, voltage-feedback op amps. A new

internal architecture provides slew rate and full power

bandwidth previously found only in wideband cur-

rent-feedback op amps. A new output stage architec-

ture delivers high currents with a minimal headroom

requirement. These give exceptional single-supply

operation. Using a single +5V supply, the OPA3680

can deliver a 1V to 4V output swing with over 80mA

drive current and 150MHz bandwidth. This combina-

tion of features makes the OPA3680 an ideal RGB

line driver or single-supply ADC input driver.

The OPA3680’s low 6.4mA/ch supply current is pre-

cisely trimmed at 25 C. This trim, along with low

temperature drift, guarantees lower maximum supply

APPLICATIONS

current than competing products. System power may be

reduced further using the optional disable control pin.

Leaving this disable pin open, or holding it high, will

operate the OPA3680 normal. If pulled low, the

OPA3680 supply current drops to less than 300 A/ch

while the output goes into a high impedance state. This

feature may be used for either power savings or to

implement video MUX applications.
