OPA2890

BurrĆBrown Products from Texas Instruments OP A2 89 0 OPA2890 SBOS364A – DECEMBER 2007 – REVISED DECEMBER 2007 OPA 2890 Low-Power, Wideband, Voltage-Feedback OPERATIONAL AMPLIFIER with Disable 1 FEATURES FLEXIBLE SUPPLY RANGE: +3V to +12V Single Supply ±1.5V to ±6V Dual Supplies UNITY-GAIN STABLE WIDEBAND +5V OPERATION: 90MHz (G = 2V/V) OUTPUT VOLTAGE SWING: ±4.1V HIGH SLEW RATE: 400V/µs LOW QUIESCENT CURRENT: 1.1mA/ch LOW DISABLE CURRENT: 30µA/ch 2 DESCRIPTION The OPA2890 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. These capabilities give exceptional single-supply operation. Using a single +5V supply, the OPA2890 can deliver a 0.9V to 4.1V output swing with over 30mA drive current and 210MHz bandwidth. This combination of features makes the OPA2890 an ideal RGB line driver or single-supply analog-to-digital converter (ADC) input driver. The low 1.1mA/ch supply current of the OPA2890 is precisely trimmed at +25°C. This trim, along with low temperature drift, ensures lower maximum supply current than competing products. System power may be reduced further using the optional disable control pin (MSOP-10 package only). Leaving this disable pin open, or holding it high, operates the OPA2890 normally. If pulled low, the OPA2890 supply current drops to less than 30µA/ch while the output goes i...
