DESCRIPTION
The OPA2691 sets a new level of performance for broadband dual
current feedback op amps. Operating on a very low 5.1mA/ch supply
current, the OPA2691 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 OPA2691 can
deliver a 1V to 4V output swing with over 120mA drive current and
150MHz bandwidth. This combination of features makes the
OPA2691 an ideal RGB line driver or single supply Analog-to-Digital
Converter (ADC) input driver.
+12V
The OPA2691鈥檚 low 5.1mA/ch supply current is precisely trimmed at
25擄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
(SO-14 only). Leaving this disable pin open, or holding it HIGH,
gives normal operation. If pulled LOW, the OPA2691 supply current
drops to less than 150碌A/ch while the output goes into a high
impedance state. This feature may be used for power savings.
