DESCRIPTIONThe OPA691 sets a new level of performance for broadband
current feedback op amps. Operating on a very low 5.1mA
supply current, the OPA691 offers a slew rate and output
power normally associated with a much higher supply cur-
rent. A new output stage architecture delivers a high output
current with minimal voltage headroom and crossover distor-
tion. This gives exceptional single-supply operation. Using a
single +5V supply, the OPA691 can deliver a 1V to 4V output
swing with over 150mA drive current and 190MHz band-
width. This combination of features makes the OPA691 an
ideal RGB line driver or single-supply Analog-to-Digital Con-
verter (ADC) input driver.
The OPA691’s low 5.1mA supply current is precisely trimmed
at 25°C. This trim, along with low drift over-temperature,

products. 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
OPA691 supply current drops to less than 150μA while the
output goes into a high impedance state. This feature may be
used for power savings.
