DESCRIPTION
The OPA3691 sets a new level of performance for broad-
band triple current-feedback op amps. Operating on a very
low 5.1mA/ch supply current, the OPA3691 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 head-
room and crossover distortion. This gives exceptional single-
supply operation. Using a single +5V supply, the OPA3691
can deliver a 1V to 4V output swing with over 120mA drive
current and 150MHz bandwidth. This combination of fea-
tures makes the OPA3691 an ideal RGB line driver or
single-supply Analog-to-Digital Converter (ADC) input driver.
The OPA3691鈥檚 low 5.1mA/ch supply current is precisely
trimmed at 25擄C. This trim, along with low drift over tem-
perature, ensures lower maximum supply current than com-
peting 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 OPA3691 supply current drops to less than
150碌A(chǔ)/ch while the output goes into a high impedance
state. This feature may be used for power savings.
