DESCRIPTION
The OPA680 represents a major step forward in unity gain
stable, voltage feedback op amps. A new internal architec-
ture 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 mini-
mal headroom requirement. These combine to give excep-
tional single supply operation. Using a single +5V supply,
the OPA680 can deliver a 1V to 4V output swing with over
100mA drive current and 150MHz bandwidth. This combi-
nation of features makes the OPA680 an ideal RGB line
driver or single supply ADC input driver.
The OPA680’s low 6.4mA supply current is precisely
trimmed at 25°C. This trim, along with low temperature
drift, guarantees lower maximum supply current than com-
peting 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 OPA680 normally.
If pulled low, the OPA680 supply current drops to less than
300µA while the output goes to a high impedance state. This
feature may be used for either power savings or to imple-
ment video MUX applications.

ELECTROSTATIC
DISCHARGE SENSITIVITY
Electrostatic discharge can cause damage ranging from perfor-
mance degradation to complete device failure. Burr-Brown Corpo-
ration 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.
