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

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/

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

driver.

APPLICATIONS

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
