A new ±2.5V to ±5V Dual Supply internal architecture provides slew rate and full-power bandwidth previously found only in wideband, • UNITY-GAIN STABLE: 500MHz (G = 1) current-feedback op amps. A new output stage • HIGH OUTPUT CURRENT: 190mA architecture delivers high currents with a minimal • OUTPUT VOLTAGE SWING: ±4.0V headroom requirement. These combine to give exceptional single-supply operation. Using a single • HIGH SLEW RATE: 1800V/µs +5V supply, the OPA690 can deliver a 1V to 4V • LOW SUPPLY CURRENT: 5.5mA output swing with over 150mA drive current and • LOW DISABLE CURRENT: 100µA 150MHz bandwidth. This combination of features makes the OPA690 an ideal RGB line driver or • WIDEBAND +5V OPERATION: 220MHz (G = 2) single-supply Analog-to-Digital Converter (ADC) input driver. APPLICATIONS • VIDEO LINE DRIVING The low 5.5mA supply current of the OPA690 is precisely trimmed at +25°C. This trim, along with low • xDSL LINE DRIVER/RECEIVER temperature drift, gives lower maximum supply • HIGH-SPEED IMAGING CHANNELS current than competing products. System power may • ADC BUFFERS be reduced further using the optional disable control • PORTABLE INSTRUMENTS pin. Leaving this disable pin open, or holding it HIGH, will operate the OPA690 normally. If pulled LOW, the • TRANSIMPEDANCE AMPLIFIERS OPA690 supply current drops to less than 100mA • ACTIVE FILTERS while the output goes to a high-impedance state. This feature may be used for power savings.
