Dual Wideband, Current-Feedback
OPERATIONAL AMPLIFIER With Disable
FEATURES
q FLEXIBLE SUPPLY RANGE:
+5V to +12V Single Supply
±2.5V to ±6V Dual Supply
q WIDEBAND +5V OPERATION: 190MHz (G = +2)
q UNITY-GAIN STABLE: 280MHz (G = 1)
q HIGH OUTPUT CURRENT: 190mA
q OUTPUT VOLTAGE SWING: ±4.0V
q HIGH SLEW RATE: 2100V/µs
q LOW SUPPLY CURRENT: 5.1mA/ch
q LOW DISABLED CURRENT: 150µA/ch
DESCRIPTION
The OPA2691 sets a new level of performance for broadband dual
current-feedback op amps. Operating on a very low 5.1mA/ch
supply current, the OPA2691 offers a slew rate and output power
normally associated with a much higher supply current. A new
output stage architecture delivers a high output current with minimal
voltage headroom and crossover distortion. This gives exceptional
single-supply operation. Using a single +5V supply, the OPA2691
can deliver a 1V to 4V output swing with over 150mA drive current
and 190MHz bandwidth. This combination of features makes the
OPA2691 an ideal RGB line driver or single-supply Analog-to-Digital
Converter (ADC) input driver.

APPLICATIONS
q xDSL LINE DRIVER / RECEIVER
q MATCHED I/Q CHANNEL AMPLIFIER
q BROADBAND VIDEO BUFFERS
q HIGH-SPEED IMAGING CHANNELS
q PORTABLE INSTRUMENTS
q DIFFERENTIAL ADC DRIVERS
q ACTIVE FILTERS
q WIDEBAND INVERTING SUMMING
The OPA2691’s low 5.1mA/ch supply current is precisely trimmed at
25°C. This trim, along with low drift over temperature, ensures lower
maximum supply current than competing products. System power
may be further reduced by using the optional disable control pin
(SO-14 only). Leaving this disable pin open, or holding it HIGH,
gives normal operation. If pulled LOW, the OPA2691 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.

ELECTROSTATIC
DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Texas Instru-
ments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling
and installation procedures can cause damage.
ESD damage can range from subtle performance degradation
to complete device failure. Precision integrated circuits may be
more susceptible to damage because very small parametric
changes could cause the device not to meet its published
specifications.
