The OPA3691 sets a new level of performance for broadband,
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 headroom
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 features
makes the OPA3691 an ideal RGB line driver or
single-supply Analog-to-Digital Converter (ADC) input driver.
The OPA3691‘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. Leaving this disable
pin open, or holding it HIGH, gives normal operation. If
pulled LOW, the OPA3691 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.
