DESCRIPTION
The OPA2680 represents a major step forward in unity
gain stable, voltage feedback op amps. A new internal
architecture provides slew rate and full power band-
width previously found only in wideband current feed-
back op amps. A new output stage architecture delivers
high currents with a minimal headroom requirement.
These combine to give exceptional single supply opera-
tion. Using a single +5V supply, the OPA2680 can
deliver a 1V to 4V output swing with over 100mA drive
current and 150MHz bandwidth. This combination of
features makes the OPA2680 an ideal RGB line driver
or single supply ADC input driver.
The OPA2680’s low 6.4mA/ch. supply current is pre-
cisely trimmed at 25°C. This trim, along with low tem-
perature drift, guarantees lower maximum supply current
than competing products. System power may be reduced
further using the optional disable control pin (SO-14
package only). Leaving this disable pin open, or holding
it high, will operate the OPA2680N normally. If pulled
low, the OPA2680N supply current drops to less than
600µA while the output goes into a high impedance state.
