DESCRIPTION  
The OPA3692 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 5.1mA/ch  
supply current, the OPA3692 offers a slew rate and output  
power normally associated with a much higher supply cur-  
rent. A new output stage architecture delivers high output  
current with minimal headroom and crossover distortion.  
This gives exceptional single-supply operation. Using a  
single +5V supply, the OPA3692 can deliver a 1V to 4V  
output swing with over 120mA drive current and > 200MHz  
bandwidth. This combination of features makes the OPA3692  
an ideal RGB line driver or single-supply, triple Analog-to-  
Digital Converter (ADC) input driver.

The low 5.1mA/ch supply current of the OPA3692 is precisely  
trimmed at +25°C. This trim, along with low drift over tempera-  
ture, ensures lower maximum supply current than competing  
products that report only a room temperature nominal supply  
current. System power can 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  
OPA3692 supply current drops to less than 150µA/ch while  
the output goes into a high-impedance state. This feature  
may be used for power savings.
