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 150 A/ch while
the output goes into a high-impedance state. This feature
may be used for power savings.
