FEATURES
DESCRIPTION
2
• FLEXIBLE SUPPLY RANGE:
The OPA2890 represents a major step forward in
+3V to +12V Single Supply
unity-gain stable, voltage-feedback op amps. A new
±1.5V to ±6V Dual Supplies
internal architecture provides slew rate and full-power
• UNITY-GAIN STABLE
bandwidth previously found only in wideband,
• WIDEBAND +5V OPERATION: 90MHz
current-feedback op amps. These capabilities give
(G = 2V/V)
exceptional single-supply operation. Using a single
+5V supply, the OPA2890 can deliver a 0.9V to 4.1V
• OUTPUT VOLTAGE SWING: ±4.1V
output swing with over 30mA drive current and
• HIGH SLEW RATE: 400V/μs
210MHz bandwidth. This combination of features
• LOW QUIESCENT CURRENT: 1.1mA/ch
makes the OPA2890 an ideal RGB line driver or
single-supply analog-to-digital converter (ADC) input
• LOW DISABLE CURRENT: 30μA/ch
driver.
APPLICATIONS
The low 1.1mA/ch supply current of the OPA2890 is
• VIDEO LINE DRIVING
precisely trimmed at +25°C. This trim, along with low
temperature drift, ensures lower maximum supply
• xDSL LINE DRIVERS/RECEIVERS
current than competing products. System power may
• HIGH-SPEED IMAGING CHANNELS
be reduced further using the optional disable control
• ADC BUFFERS
pin (MSOP-10 package only). Leaving this disable pin
• PORTABLE INSTRUMENTS
open, or holding it high, operates the OPA2890
normally. If pulled low, the OPA2890 supply current
• TRANSIMPEDANCE AMPLIFIERS
drops to less than 30μA/ch while the output goes into
• ACTIVE FILTERS
a high-impedance state.
