DESCRIPTION
The OPA3681 sets a new level of performance for broadband
triple current-feedback op amps. Operating on a very low
6mA/ch supply current, the OPA3681 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 distor-
tion. This gives exceptional single-supply operation. Using a
single +5V supply, the OPA3681 can deliver a 1V to 4V output
swing with over 100mA drive current and 150MHz bandwidth.
This combination of features makes the OPA3681 an ideal RGB
line driver or single-supply ADC input driver.
The OPA3681's low 6mA/ch supply current is precisely trimmed
at 25
C. This trim, along with low drift over temperature,
guarantees lower guaranteed maximum supply current than
competing 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 OPA3681 supply current drops to less than 300
A/ch while
the output goes into a high impedance state. This feature may be
used for power savings or for video MUX applications.

ELECTROSTATIC
DISCHARGE SENSITIVITY
Electrostatic discharge can cause damage ranging from perfor-
mance degradation to complete device failure. Burr-Brown Corpo-
ration recommends that all integrated circuits be handled and stored
using appropriate ESD protection methods.
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 published specifications.
The information provided herein is believed to be reliable; however, BURR-BROWN assumes no responsibility for inaccuracies or omissions. BURR-BROWN assumes
no responsibility for the use of this information, and all use of such information shall be entirely at the user's own risk. Prices and specifications are subject to change
without notice. No patent rights or licenses to any of the circuits described herein are implied or granted to any third party. BURR-BROWN does not authorize or warrant
