• 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.

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 30

µA/ch while the output goes into

• ACTIVE FILTERS

a high-impedance state.
