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.
