OPA690IDR Datasheet

Linear - Amplifiers - Instrumentation, OP Amps, Buffer Amps


The OPA690IDR 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 combine to give exceptional single-supply operation. Using a single +5V supply, the OPA690IDR can deliver a 1V to 4V output swing with over 150mA drive current and 150MHz bandwidth.This combination of features makes the OPA690IDR an ideal RGB line driver or single-supply Analog-to-Digital Converter (ADC) input driver. The OPA690’s low 5.5mA supply current is precisely trimmed at 25°C. This trim, along with low temperature drift, gives 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 OPA690IDR normally. If pulled LOW, the OPA690 supply current drops to less than 100µA while the output goes to a high impedance state. This feature may be used for power savings.
