DESCRIPTION
The OPA2690 represents a major step forward in
unity-gain stable, voltage-feedback op amps. A new
internal architecture provides slew rate and full-power
bandwidth previously found only in wideband,
current-feedback op amps. A new output stage
architecture delivers high currents with a minimal
headroom requirement. These give exceptional
single-supply operation. Using a single +5V supply, the
OPA2690 can deliver a 1V to 4V output swing with over
120mA drive current and 150MHz bandwidth. This
combination of features makes the OPA2690 an ideal
RGB line driver or single-supply Analog-to-Digital
Converter (ADC) input driver.
The low 5.5mA/ch supply current of the OPA2690 is
precisely trimmed at +25°C. This trim, along with low
temperature drift, ensures lower maximum supply current
than competing products. System power may be reduced
further using the optional disable control pin. Leaving this
disable pin open, or holding it HIGH, will operate the
OPA2690I-14D normally. If pulled LOW, the
OPA2690I-14D supply current drops to less than
200µA/ch while the output goes to a high-impedance
state.
