DESCRIPTION
The OPA682 provides an easy to use, broadband fixed gain
buffer amplifier. Depending on the external connections, the
internal resistor network may be used to provide either a
fixed gain of +2 video buffer or a gain of +1 or 1 voltage
buffer. Operating on a very low 6mA supply current, the
OPA682 offers a slew rate and output power normally
associated with a much higher supply current. A new output
stage architecture delivers high output current with a mini-
mal headroom and crossover distortion. This gives excep-
tional single supply operation. Using a single +5V supply,
the OPA682 can deliver a 1V to 4V output swing with over
100mA drive current and 200MHz bandwidth. This combi-
nation of features makes the OPA682 an ideal RGB line
driver or single supply ADC input driver.

The OPA682's low 6mA supply current is precisely trimmed
at 25
C. This trim, along with low drift over temperature,
guarantees lower maximum supply current than competing
products that report only a room temperature nominal supply
current. 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
OPA682 supply current drops to less than 320
A while the
output goes into a high impedance state. This feature may be
used for either power savings or for video MUX applications.
