OPA3690 (ACTIVE)

Triple, Wideband, Voltage-Feedback Operational Amplifier with Disable

 

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 200µA/ch while the output goes to a high-impedance state. This feature may be used for power savings.
