The OPA3682 provides an easy-to-use, broadband fixed
gain, triple 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/ch supply current, the OPA3682 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 minimal headroom and
crossover distortion. This gives exceptional single-sup-
ply operation. Using a single +5V supply, the OPA3682
can deliver a 1V to 4V output swing with over 100mA
drive current and 200MHz bandwidth. This combination
of features makes the OPA3682 an ideal RGB line driver
or single-supply, triple ADC input driver.
The OPA3682’s low 6mA/ch 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 tempera-
ture 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 OPA3682 supply current drops
to less than 320µA/ch while the output goes into a high
impedance state. This feature may be used for either power
savings or for video MUX applications.
