The OPA2682’s low 6mA/ch supply current is precisely
trimmed at 25°C. This trim, along with low drift over tempera-
ture, 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
OPA2682 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.
DESCRIPTION
The OPA2682 provides an easy to use, broadband fixed
gain, dual buffer amplifier. Depending on the external con-
nections, the internal resistor network may be used to pro-
vide 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 OPA2682 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 minimal headroom and crossover distortion. This
gives exceptional single supply operation. Using a single
+5V supply, the OPA2682 can deliver a 1V to 4V output
swing with over 100mA drive current and 200MHz band-
width. This combination of features makes the OPA2682 an
ideal RGB line driver or single-supply ADC input driver.
