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 singlesupply operation. Using a single +5V supply, the OPA2691 can
deliver a 1V to 4V output swing with over 120mA drive current and
150MHz bandwidth. This combination of features makes the
OPA2691 an ideal RGB line driver or single supply Analog-to-Digital
Converter (ADC) input driver.

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.

NOTE:: (1) Stresses above those listed under “Absolute Maximum Ratings”
may cause permanent damage to the device. Exposure to absolute maximum
conditions for extended periods may affect device reliability. (2) Packages
must be derated based on specified θJA. Maximum TJ must be observed.
ELECTROSTATIC
DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Texas Instruments 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.
