Wideband, Current Feedback
OPERATIONAL AMPLIFIER With Disable
TM
DESCRIPTION
The OPA681 sets a new level of performance for broadband
current feedback op amps. Operating on a very low 6mA
supply current, the OPA681 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
distortion. This gives exceptional single-supply operation.
Using a single +5V supply, the OPA681 can deliver a 1V to
4V output swing with over 100mA drive current and 150MHz
bandwidth. This combination of features makes the OPA681
an ideal RGB line driver or single-supply ADC input driver.
The OPA681’s low 6mA supply current is precisely trimmed
at 25
°
C. This trim, along with low drift over temperature,

HIGH SFDR IF AMPLIFIER
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 OPA681 supply current drops to less than 320
μ
A while the
output goes into a high impedance state. This feature may be
used for either power savings or for video MUX applications.
