● ADC BUFFERS  
● ACTIVE FILTERS  
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 320µA 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 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.
