DESCRIPTION
The OPA3690 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 OPA3690 can deliver a 1V to 4V output swing
with over 120mA drive current and 150MHz
bandwidth. This combination of features makes the
OPA3690 an ideal RGB line driver or single-supply
Analog-to-Digital Converter (ADC) input driver.
The low 5.5mA/ch supply current of the OPA3690 is
precisely trimmed at +25°C. This trim, along with low
temperature drift, provides 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 OPA3690 normally. If pulled LOW,
the OPA3690 supply current drops to less than
200mA/ch while the output goes to a high-impedance
state. This feature may be used for power savings.
