OPA692

SBOS236E – MARCH 2002 – REVISED DECEMBER 2008

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

150

µA while the I/O pins go into a high-impedance state.
