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 cur­rent-feedback op amps. A new output stage architec­ture 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 combina­tion 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 pre­cisely trimmed at 25°C. This trim, along with low
temperature drift, guarantees lower maximum supply

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 300µA/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.

ELECTROSTATIC
DISCHARGE SENSITIVITY

Electrostatic discharge can cause damage ranging from perfor­mance degradation to complete device failure. Burr-Brown Corpo­ration recommends that all integrated circuits be handled and stored
using appropriate ESD protection methods.

ESD damage can range from subtle performance degradation to
complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes
could cause the device not to meet published specifications.
