DESCRIPTION
The OPA692 provides an easy to use, broadband fixed gain
video buffer amplifier. Depending on the external connec-
tions, 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 supply cur-
rent, the OPA692 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-supply operation. Using a single +5V
supply, the OPA692 can deliver a 1V to 4V output swing with
over 120mA drive current and > 200MHz bandwidth. This
combination of features makes the OPA692 an ideal RGB
line driver or single-supply Analog-to-Digital Converter (ADC)
input driver.
The low 5.1mA supply current for the OPA692 is precisely
trimmed at +25°C. This trim, along with low drift over tem-
perature, ensures a lower maximum supply current than
competing products that report only a room temperature
nominal supply current. System power may be further re-
duced by using the optional disable control pin. Leaving this
disable pin open, or holding it HIGH, gives normal operation.
If pulled LOW, the OPA692 supply current drops to less than
150µA while the I/O pins go into a high-impedance state.
