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
μ
A/ch while
the output goes into a high impedance state. This feature may be
used for power savings or for video MUX applications.
